On fixed costs - rent will decrease. That's about 200k per year.

Variable costs - wages are about 12% of revenue, although I'd imagine this changes depending on the product mix.
Similarly, the product mix will impact the cost of inventory/supply, but not by a whole lot.

I wouldn't model things according to guidance given by management. Although it's likely they're talking revenue, they virtually always exceed their conservative forecasts. I'm sure management have their internal forecasts/goals which would be much higher than what they release to the ASX.
