I need to cut a 30 mm hole in some 0.8 mm aluminium.
I have various hole cutting devices such as Forstner bits but they are for

Is there anything clever for cutting holes in metal sheets?

A stepped drill will do if you cannot get a punch. This one has steps at 3mm so third from the end should be 30mm
