Sydney's big wet has forced the transfer of two Toyota Cup games but all NRL matches will go ahead as planned this weekend.

Friday night's National Youth Competition fixture between Canterbury and Parramatta will now be played at Wentworthville on Sunday, with officials concerned the heavy traffic could cut up the ANZ Stadium playing surface.

As well as hosting the vital NRL clash between the Eels and Bulldogs, ANZ Stadium will also host Saturday night's rugby union Tri Nations match between Australia and South Africa.

Torrential rain has battered the coastal regions of NSW for several days, with more wet weather forecast for the weekend.

Saturday night's Toyota Cup clash between Wests Tigers and Sydney Roosters has been shifted to Campbelltown Stadium to preserve the Leichhardt Oval surface for the NRL fixture between the two clubs.
