The centrepiece of the old miner's hut was this solid fuel stove, a Metters Bega. Although coal may have been used in it occasionally it was more likely to be wood fired, as the lumps of wood surrounding it attest. I have no idea what the plastic bags are supposed to represent but it's unlikely that they're period-appropriate. (And in any case you can't normally see them in the darkness of the cabin.)

Metters was an Australian appliance company which was founded in South Australia in the late 1800's and subsequently became a national brand. Although Metters appliances weren't unknown in the city back in the early to middle of last century, they seem to have been constructed more with the bush in mind. The company was taken over by Email in the mid 1970's and the brand was phased out of use around a decade after that.

The oven was the only source of heating, and also served for cooking, as a supplementary form of light, and was useful for drying mining clothes since it was always wet underground.

Note too the basic water tank to the left of the oven, and the bucket further beyond that. There was also a wash basin nearby, which will be seen in a later shot.
