However, the recovery has not been as fast as Ardent would have liked, prompting the company to book a further impairment charge against Dreamworld of A$22.8m ($24.5m), which the company flagged earlier in February.
Ardent's chief executive of theme parks, Craig Davidson, said Dreamworld's visitor numbers were increasing now that all its attractions were operating following safety and engineering reviews.
"Now I see a clean runway: we've got every piece of the park operating, and we're back to our normal scheduling of down-times, we've got some new attractions coming, and I think we're going to see the trend continue," Davidson said.
And, Ardent expects that tiger cubs born in late January and the completion of Corroboree stage II - an interactive depiction of Indigenous culture - will also boost visitor numbers in the lead-up to the Commonwealth Games.
A DreamWorks walk-through attraction and a Flying Theatre are also set to open later in the year.
Meanwhile, Ardent has announced the appointment of Chris Morris as chief executive of Main Event, Ardent's bowling and entertainment centres business in the US which generated more than 80 per cent of the group's first-half revenue from continuing operations.
Main Event's revenue grew by 25.4 per cent to US$128 million ($174.8 million) as 10 new centres opened in 2017 made contributions, and the centres attracted more walk-in customers.
Ardent's net loss of A$15.6m for the period from July 1 to December 26 is less than a third of its A$49.3m net loss for the six months to December 31, 2016.
The result - for 179 days, compared to the previous first-half's 184 days - includes the Dreamworld impairment charge.
But Ardent expects to trade profitably in the second half, generating both positive earnings and profit.
