Hospital operator Wakefield Health has seen a 63% rise in headline profit to $6.1 million for the six months to September.
Once last year's losses from selling its investment in P3 Research are excluded, the profit from continuing operations rose 36%.
Revenue rose 12% to almost $41 million, as it saw more patients and made greater use of its operating theatres, while keeping a lid on costs.
Looking ahead, Wakefield is unsure how the slowing economy will affect its business, though it admits it may dampen private surgery and the uptake of health insurance.
