What is the dress code for Luxe Lounge at the Gabba?

Going to cricket at Luxe Lounge at the Gabba tomorrow, I have been a few times, however wanting to confirm dress code,

I called the Gabba and the Woman on the phone told me she had no idea what the luxe lounge was and to call ticketek 😳

So thought i’d ask real people and get a proper answer

Thank you
