Hi all from Aussie

It is too late now of course, but some thin wire loops cast into the base of the dome work well to wire in the mesh. Failing this you can probably hold it in with string and snip it off across the entry once the vermicrete has hardened.
Try to let the weather ( sun and wind) dry the vermicrete and leave it for a week(per layer) to dry. Cure the oven before doing the render. Others may do it differently, but this is the way I do it. You don't want steam pressure build up in the insulation layer or it will crack the outer shell.
