The weather bureau's monthly rainfall statistics for June show Victoria's Wimmera-Mallee received about double its usual average.
Heavy rain during the first couple of weeks of June saw records breaking across the region.
The western Victorian town of Nhill had its highest ever rainfall on record last month with 125 millimetres, more that half of which fell in just one day.
Heavy rain throughout the first two weeks of June also saw the average rainfall for the month in the Wimmera rise by 183 per cent and more than 200 per cent in the Mallee.
Swan Hill topped its previous best monthly figure and St Arnaud had its highest rainfall since 1898 with 112mm.
Kaniva, Horsham and Hopetoun also broke their previous highs for June but were all topped by Jeparit with 137mm.
