Melbourne-made video game Cult of the Lamb has made it to the top of global sales charts within days of its release.

"It's just blown up, it's been pretty crazy," developer Julian Wilton from Massive Monster told AAP.

Since its global launch in the early hours of Friday morning, the game reached number one on the US Switch store, the main outlet for Nintendo games, and Wilton has high hopes for early sales figures.

"I wouldn't be surprised in the first month if we hit like a million units, which is just crazy," he said.

On PC gaming platform Steam, Cult of the Lamb has seen hundreds of thousands of downloads, and while Wilton can't reveal the exact figures due to Massive Monster's backing by UK-listed Devolver Digital, pre-sales numbers show the game has already recouped its investment costs.

It's rare for an Australian-made game to see such global success, with 2017's Hollow Night by Adelaide's Team Cherry a recent example.

Gamers have given Cult of the Lamb the thumbs-up so far, with more than 8000 positive Steam reviews, and some predicting it will become a cult classic.

But the large number of gamers trying the game have uncovered bugs and the Massive Monster team is working to fix them, devoting the next 12 months to updates and new content.

"There's just so many people playing the game that there's no way you can find some of these bugs that people are finding," Wilton said.

Some of the problems that come with Massive Monster's success are nice to have.

"We just got to figure out what to do with all this money now," Wilton joked.

In 2020/21 Australian game development studios made $226 million, with 82 per cent of that money from overseas markets, according to figures from the Interactive Games and Entertainment Association.

Recent Aussie hits include Unpacking by Witch Beam in Brisbane, Hollow Knight by Team Cherry in Adelaide, and in Melbourne, Untitled Goose Game by House House and Florence by the studio Mountains.

The federal government offered tax breaks for developers in 2021 and pledged fresh funding through Screen Australia in March.

An inspection is underway on an enclosure at Adelaide Zoo after the escape of a red panda.

The zoo says Ravi is now safely back in its health unit after being rescued from a tree in the Adelaide parklands on Sunday.

He was brought down with a tranquilliser dart after resisting attempts to lure him with food.

Ravi had been missing from the zoo since Friday.

"Red pandas are master climbers and while we take every effort to provide a secure area, the combination of panda prowess coupled with the weather helped him to go on an adventure," zoo officials said.

"A full inspection of Ravi's exhibit will be underway immediately."

That will include reviewing CCTV footage to try to determine how he got out of his main enclosure, and how he breached the zoo's external fence.

The zoo said red pandas posed no risk to humans and the small mammals, native to the eastern Himalayas and southwestern China, were considered an endangered species partly due to habitat loss.

Ravi was born at Adelaide Zoo seven years ago, but only returned to South Australia last week after spending several years at Australia Zoo in Queensland.

Queensland businesses are less confident about the next 12 months despite enjoying solid sales and revenue.

Some 42 per cent of businesses say sales and revenue rose in the June quarter, according to the Chamber of Commerce and Industry of Queensland (CCIQ).

However, their confidence has fallen as rising labour and operating costs continued to eat away profits.

The CCIQ's Cherie Josephson says half of the businesses surveyed reported a fall in profitability over the quarter.

"We saw a decoupling of business performance and confidence; a significant deterioration of business confidence but solid business performance with similar expectations for the September quarter," she said.

While businesses' main concerns are labour and operating costs rising, other factors hitting confidence.

Ms Josephson said rising inflation, interest rates, energy costs as well as supply chain disruptions had dented sentiment.

More than nine in 10 businesses reported rising fuel prices and almost 83 per cent said their insurance costs jumped in the June quarter.

Supply chain and logistics costs increased for 79.4 per cent of firms surveyed.

In the three months to June, electricity, raw materials and stock costs rose for more than 72 per cent of respondents.

"While sales are strengthening, businesses' ability to grow is being held back by continued rising operating costs," Ms Josephson said.

"Businesses need certainty about what support they'll be offered for rising operating costs, including energy, insurance and fuel costs if there was to be any sustained improvement in business confidence over the next 12 months."

Canberra Airport has resumed normal operations and a man is in custody after a shooting incident inside the terminal prompted its evacuation.

A man was arrested at the airport after firing as many as five shots inside, some leaving bullet holes in airport windows, just after 1.30pm on Sunday.

The man was taken to a Canberra police station, with the firearm seized by officers.

Police are yet to establish a motive behind the incident, but ACT Detective Acting Superintendent Dave Craft said the shots were not aimed at anyone.

Officers are yet to provide a name or age of the man, but Det Supt Craft said he was believed to be the only person responsible for the incident.

Det Supt Craft said the man did not go through airport security and sat near the check-in counters before firing shots at the windows.

The airport was evacuated shortly after the shooting incident, with parts of the terminal locked down.

Passengers who had boarded planes were stuck on the tarmac for hours before being allowed to disembark.

The airport resumed normal operations before 5pm. "Please check your travel plans directly with your airline if you are travelling today," its management said in a tweet.

Police said there was no ongoing threat to the community or to other passengers.

Prime Minister Anthony Albanese said he had been briefed on the airport incident.

Finance Minister and ACT senator Katy Gallagher said she had been shocked by the event.

"Our local airport is such an important part of the Canberra community and it must have been terrifying for everyone," she said on Twitter.

"Thanks so much to the first responders for keeping everyone safe."
