Overseas duo Albert Kelly and Maurice Blair have declared their commitment to Hull KR for 2016 by discarding release clauses in their contracts.
The former Gold Coast Titans team-mates had options to return to the NRL at the end of their first season in Super League but the deadline expired on Sunday and Rovers say both players have opted to stay at the club next season.
The announcement comes two months after club captain Terry Campese agreed a two-year extension to his initial 12-month contract.
Hull KR coach Chester said: "It is really important for us moving forwards that we retain our best players and Albert and Bobby certainly fit into that category.
"Bobby has done a great job in the halves over the last month and we've already seen his quality and versatility at centre and in the back row. Albert is a special talent who has made a huge impact on the competition and he is a player that supporters are excited to watch.
"For both players to want to stay at the club shows we are heading in the right direction and really highlights the spirit and togetherness within the squad."
Kelly said: "Bobby and I are good friends and I know I speak for the both of us when I say we are really enjoying our time over here at Hull KR and the style of rugby played in the Super League competition.
"We're enjoying living in the UK, as are my family, and we're exciting about being part of this club."
Thousands of rugby league fans will make the journey up to Newcastle tomorrow for the annual Magic Weekend event.
One of the most anticipated fixtures at St James' Park will be the meeting of Hull FC and Hull Kingston Rovers.
Despite Rovers coming out on top the last time the sides met in March their head coach Chris Chester believes his team are underdogs:
Meanwhile the final match of the weekend sees Super League leaders Leeds take on third placed Wigan, and skipper Kevin Sinfield says his team are out for revenge for their previous two Magic Weekend defeats:

Hull KR turned the tables in sensational fashion to knock Wigan out of the Ladbrokes Challenge Cup with a nail-biting 16-12 victory.
Just a fortnight after suffering a 60-0 humiliation in Super League, Rovers exacted sweet revenge in a rousing sixth-round tie at Leigh Sports Village.
Despite an error-strewn performance, the Warriors were on course for a record-extending 20th trophy when leading 12-10 with eight minutes to go.
However, Hull KR centre Ken Sio pounced on the latest of a series of handling errors, this time from England international Dan Sarginson, to go over for the match-winning try.
Hull Kingston Rovers have announced that they will offer fans who made the trip to Wigan and saw the Robins crash to a 60-0 defeat free tickets to the Ladbrooks Challenge Cup tie on May 15th.
Chris Chester who admitted on Friday night that what fans witnessed “was not a Hull KR performance” said he wanted to do his bit to repay those supporters who made the trip in an unprecedented move.
I looked across to the away end and saw the fans doing the conga while we trailed 60-0 and thought they don’t deserve this. We’ve had a chat as a club and have decided that the right thing to do as a one-off is to pay for the fans who made the trip on Friday a ticket to the Cup game in two weeks. That’s a massive game for us so we want to take a big and noisy following and make it a real Cup tie. As I’ve already said I am confident it will be a totally different game to what we saw on Friday.
Friday was a tough day for everyone at the club but the unwavering support coming from the away end of the DW Stadium was nothing short of phenomenal. We know fans pay their hard earned money to follow us home and away and we never take that for granted. That was our 4th away game in a row on the back of an expensive weekend away to Catalan for many and it would have been easy for them to stay at home and watch it on TV. Sport is of course notorious for having ups and downs so we certainly don’t intend to make this a precedent but we felt we had to do something to thank those fans for their ongoing support as a one-off gesture because of these unique circumstances.
Hull KR have given goalkicking winger Josh Mantellato permission to miss Friday's Super League trip to Wigan in order to be best man at his brother's wedding in Australia.
Mantellato, an Italy international, has been a big success in his first season in Super League so far and is the leading points scorer but Rovers say they were made aware of the situation before he signed for them last November.
Mantellato, who scored 30 points in the Robins' Challenge Cup win over Bradford earlier this month, flew to Australia after last Saturday's game against Catalans and will be back in England on Sunday ready for the club's home game against Wakefield next Thursday

Hull KR prop James Green will miss the derby with Hull FC on Thursday after being banned for a shoulder charge.
Green was charged by the Rugby Football League's match-review panel with the grade B offence on his former team-mate Travis Burns, the St Helens stand-off, during his side's 24-20 win over the champions on Friday and submitted an early-guilty plea.
Green will be available for the Robins' Easter Monday home game against Huddersfield while centre Darrell Goulding will be eligible to play in both Easter fixtures after submitting an early guilty plea to a minor grade A trip on Saints centre Jordan Turner.
Former England and Great Britain rugby league captain Jamie Peacocck is to retire from playing at the end of the season to become Football Manager at Hull Kingston Rovers
The Leeds Rhinos prop confirmed his retirement from rugby league today after completing a tenth and final campaign with the Headingley club.
Peacock, who has won eight Super League Grand Finals as well as making over 500 appearances for Leeds, Bradford, Yorkshire, England and Great Britain, will then move to the KC Lightstream Stadium to take up his new challenge from next season.
“The Rhinos are a blueprint for a successful sporting business and the challenge for me now is to take those lessons and try and implement my own thoughts in a new environment.
“Hull KR are a club with huge potential within a city that is rugby league mad and having invested wisely in their facilities in recent years. I know a number of people over there already and I am looking forward to working with Chris Chester, Willie Poching, Mike Smith and Neil Hudgell in my new role.
“Whenever we have gone over there to play, it is clear Rovers have a fanatical supporter base. I think it is vital that you have a hard core of good people who want the club to succeed to be able to build and plan for development in the future.
“Now that I have the next chapter of my career finalised, I am fully focused on finishing my time with Leeds as strongly as possible and leaving my home town club in the best possible position.”
A winner of multiple Grand Final, Challenge Cup and World Club Challenge matches throughout his career, Peacock is a former England and Great Britain captain who was crowned Man of Steel in 2003 and awarded his MBE three years ago for his services to the sport.
Hull KR chairman Neil Hudgell added: “We are delighted to have secured Jamie to the full-time position of Football Manager for the next two years.
“He is a proven champion at the highest level in our sport and we look forward to working with him, drawing on his experiences and contacts and generally raising the profile and performance of the club in key areas.
“I’m sure he will have a big role to play in helping to attract young English talent to Hull Kingston Rovers and in helping to develop a winning culture on and off the field.”
“I think this is an inspired appointment by Hull KR and I know Jamie will be very good at what will be a very different challenge.
“He has been at the heart of all our success over the past decade and his performances and influence at the club cannot be overestimated.
" He will leave a lasting legacy and all our best wishes will be with him when he swaps his training kit for a new suit at the end of the season.”
Hull KR have announced they have released former Leeds prop Ryan Bailey with immediate effect due to personal reasons.
Bailey, 30, was one of 14 new signings made by the Robins ahead of the 2015 season but he made only one substitute appearance, in a 44-24 defeat at Wakefield in the second match of the campaign.
Rovers say Bailey was dogged by hamstring and Achilles injuries and that they reached an agreement with the player's representatives to release him to allow him "to focus on matters off the field".
I would like to thank Hull Kingston Rovers for the way they have conducted themselves during our discussions over the past few weeks. They have respected Ryan's right to privacy throughout this process and have offered him their full support. We couldn't have asked for any more during what has been a difficult time in Ryan's private life, but it's now best to move on for all parties.
Bailey joined the Robins as a direct replacement for Australian Justin Poore, who retired through injury at the end of last season.
Bailey had spent all his career at the Rhinos, with whom he won six Grand Finals, three World Club Challenge titles and the 2014 Challenge Cup in 14 seasons.
