Bright Basioni, 19 of Sherlock Avenue, Tarneit, and Deng Deng, 23, of Stable Drive, Truganina, pleaded guilty in Warrnambool Magistrates Court to shop theft and bail offences.

Lawyer Morgan Adams said the pair visited Warrnambool at the weekend to go sight-seeing.

They were caught stealing a bottle of Little Fat Lamb cider and 'Gangster' - a bottle of vodka in the shape of an automatic handgun - worth $53 from Warrnambool's Premix King on Saturday.

They were later arrested on the Melbourne-bound V/Line train.

The cider was not recovered but officers located the vodka inside Basioni's backpack.

The court heard Basioni was on bail for robbery, as well as a corrections order for affray and shop steal.

Deng was on six counts of bail and has prior convictions for robbery and armed robbery.

Magistrate Leonard Brear said the pair had taken advantage of "the leniency and decency of this court and the community in giving you further chances".

In sentencing, the magistrate said he had taken into account the two days the pair had spent in custody on remand.

He convicted them, fined them $500 each and ordered they pay compensation to the bottle shop.

"If you get into further trouble, if you keep causing this grief to other people, you keep pinching things with your mates... you'll find that one day you will get sentences that you won't like," he said.

"If you get up to these tricks again, don't expect any sympathy."

A police application to revoke their bail was refused.
