Four thieves who blew up an ATM in Sydney's eastern suburbs were forced to flee on foot after the explosion damaged their getaway car, police say.

The four males set off the explosion at the Bendigo Bank street-front ATM in Clovelly Road, Clovelly, at about 1.45am (AEDT) on Tuesday.

The bank was extensively damaged with debris spewed out across the street.

The thieves had to abandon their Audi getaway car and escaped the scene on foot.

Bomb squad officers were called in to ensure several gas cylinders found in the car were safe.

The incident was one of three ATM-explosions across Sydney during the night.

About the same time, three males were seen blowing up an ATM on Waldron Street, Chester Hill, in Sydney's west, damaging the front of a bank.

Police believe the bandits fled in a late-model silver Audi.

In the third incident, an ATM on Guildford Road at Guildford was blown up at about 2.15am.

The area of Guildford Road between Cross Street and Station Street has been cordoned off due to a large amount of debris.
