While Geoscience Australia initially reported an earthquake with a magnitude of 6.0, the head of the Seismology Research Centre Adam Pascale has said "we think it's a mag-5.8 potentially at this point in Gippsland", adding the earthquake "shook here in the northern suburbs of Melbourne for about 15-20 seconds so it's quite a significant earthquake". Geoscience Australia has since revised the magnitude to 5.9.
Further aftershocks remain a possibility, with Pascale saying "there's usually a primary and a secondary wave", and geoscientist Mark Quigley telling"for something of that size, we're talking about a fault that would be on the order of maybe 5 kilometres long and three kilometres wide. For an earthquake of that magnitude, we would expect to get hundreds of small aftershocks. We could get aftershocks in the range of 4.5 magnitude."
