The baby great white shark found washed up on a Sydney beach has undergone a health assessment and is likely to be released into the ocean on Tuesday.

The 1.5-metre shark, nicknamed "Fluffy", was spotted flailing in the surf at Shelly Beach near Manly about midday on Monday.

Attempts to drag the injured shark back into the sea failed, so rescuers moved it to a stretcher and transferred it the Fairy Bower ocean pool, where it attracted a crowd of onlookers.

The shark, which appears to have injuries to its mouth and tail, was later put in a truck and taken to Manly Sea Life Sanctuary, where it was transferred to an isolation tank and assessed overnight.
