The group, branded the "Budgie Nine", were charged with public nuisance, which carries a fine but no jail time.
The men were detained after posing in swimwear decorated with the Malaysian flag to celebrate Australian Daniel Ricciardo's win in Sunday's race.
In a letter read out in court, they apologised and expressed their "deepest regret".
They said the incident was "purely an error of judgement" on their behalf.
Among the men was Jack Walker, an aide to Australian Defence Industry Minister Christopher Pyne.
