The "Mad Monday" saga is over for the four Bulldogs players either charged by NSW Police or fined by their club after end-of-season celebrations at a Sydney hotel got out of hand in September.

On Monday in Sydney's Downing Centre Local Court, Adam Elliott and Asipeli Fine both pleaded guilty to a charge of wilful and obscene exposure, after media photographers caught them naked, singing and dancing, on an upper-level balcony.

After their lawyers made representations on their behalf, they players were handed two-year good behaviour bonds with no conviction recorded.

A group of teammates led by skipper Josh Jackson sat in the court's public gallery to show their support.

Monday's proceedings follow both the Bulldogs and the NRL penalising the main offenders in the September 3 mayhem.

Elliott, 24, and Fine, 26, were each fined $25,000 ($10,000 suspended) by the Bulldogs, while Marcelo Montoya and Zac Woolford were fined $10,000 each ($5000 suspended).

The NRL initially fined the Belmore club $250,000 but after an appeal, that was reduced by half on condition there was no other breaches of the game's Code of Conduct within the next two years.

Fine (released) and Woolford (Knights) are no longer with the club. Elliott and Montoya are both contracted until the end of 2020.
