Sydney's Wet'n'Wild theme park made a profit of almost $6 million in its first few weeks of operation.

More than 160,000 season passes were sold before its opening on December 12, generating $12.5 million in revenue for the park's operator, Village Roadshow.

Attendances have also exceeded the company's expectations, with more than 400,000 passing through the gates of the western Sydney water park up to the end of January.

While popular with the public, the park suffered an embarrassing early setback with a party scheduled to take place there on New Year’s Eve cancelled just six hours before it was due to start.
