G'day Norm,
Thanks Gadge, I had a look at the sustainability site and that is good they will take the fuels but my bigger issue is the 70/80 litres of engine oil I still have to get rid of.
Many council 'transfer stations' in Vic will accept limited [i.e. non-commercial] quantities of used engine oil for disposal, however they usually charge for this.
Maximum container size is usually 20L, and often they will keep the container too.
There's a list of those in your area here;

Knox and Westall Road both charge $1/L; Hampton Park charges $0.55/L by the look of their website price list;
