The Wanderers were the dominant side early on and hit the front in the 15th minute with a powerful strike from Jerome Polenz.
Ernie Merrick's men worked their way into the contest midway through the opening stanza but Jeremy Brockie's shot into the side-netting on the half-hour was the closest the visitors came to an equaliser before the interval.
Wanderers skipper Michael Beauchamp missed a gilt-edged chance seven minutes into the second half after a dangerous Shinji Ono free-kick before Jeremy Brockie equalised on the hour.
In the day's other game, Newcastle Jets and Perth Glory played out a 0-0 stalemate at Hunter Stadium.
The Jets controlled the match throughout and created a number of half chances without being able to convert while the Glory were content to absorb the pressure and attack on the counter.
