I'm going to assume yes anyway. Firstly because it's highly unlikely we'd come across two players named JG Ullungara.. and secondly because the stats site would chuck a wobbly if we did.
Yeah, his one First Class game was a game between Victoria and New Zealand back before Victoria got rep status. http://www.cricsim.com/site/match.php?id=180
IIRC he was one of the 1000 victorians Stormer recruited for the Allstars? I think Storer is the only survivor out of them all....excluding this guy obv now.
