"Capex expenditure in FY2020 was driven by opportunistic investment supported by long-term projects," he said.

"It was a larger investment than previous periods but will continue to support future margins."

The company made capital investment of $13.4 million in FY2020.

Capital investment will reduce in FY2021, made up of mostly sustaining capex.

"New projects may require capital investment, but will be supported through a disciplined approach," Caruso said.
