The 31-year-old powerhouse will now be on board at the Dolphins until the end of 2028 after finding a home at the club under coach Kristian Woolf, who he has a long relationship with dating back to his teenage years at Brisbane.
The powerhouse is in his 11th NRL season and has 161 NRL games to his credit and two State of Origin games for Queensland in 2021.
While at St George Illawarra in 2023 Molo pleaded guilty to a domestic violence charge of stalking or intimidation with intent to cause fear of physical or mental harm.
He has since been a model footballer on and off the field.
"Being young you make mistakes and you learn through different experiences and going through hardships," Molo said.
"Like anyone you have a choice to change or to stay the same. I chose to change in my life with my sobriety and it has paid dividends on the field as well.
"It has been three years now (off the booze). It was the best thing for me with the issues I had. I am enjoying footy and my life off the field."
Molo said he was "extremely grateful" and "genuinely happy" to have inked a new Dolphins deal.
"A lot of people thought I came back (to Queensland) because I am from Brisbane but that wasn't the case," Molo said.
"The main reason was because I have a good relationship with Woolfy. I have known him from a young age and he knows what I am about and I know what he is about as well.
"I thought he would unlock the best in me in terms of training and playing so that was the main reason."
Woolf coached Molo in the Broncos under 20s and was also his mentor at the Townsville Blackhawks.
Molo is a member of a stacked Dolphins pack that he insists can challenge for a title.
"One hundred per cent. That was another reason why I stayed because I genuinely believe we have the squad to win a comp, if not this year then next year," Molo said.
"We have a bunch of quality players and if we keep working hard week in and week out I think we can try and make that finals run."
