He's a high-patterned lowland Blotched BTS. Easy way to remember them is they look a bit like leopard print camouflage.
Lowland = Black and brown/tan colours, with some very southern variants even displaying a grey colour such as Phillip Island and Tasmanian localities
Highland = Greater black with yellow (mostly within highlands Victoria up to the Snowy Mountains periphery)
Highland Alpine = Greater black with orange/pink (Victoria and NSW Snowy Mountains region and periphery)
There's a great directory of visual examples on one of the forum threads here also.
