The Ian Potter State Theatre comes back in October after a two-year redevelopment, and the government says it is arriving six months ahead of schedule. To mark it, 18,000 free tickets are being made available for a four-day opening weekend called Housewarming.

It runs from 9 to 12 October. The bill is not a token one: the Australian Ballet, Opera Australia, Melbourne Theatre Company, Circus Oz, the Victorian College of the Arts, Emma Donovan, Eliza Hull and The Listies, plus guided tours, DJ sets, roaming performances and a laser light show.

The catch, for now

The announcement does not say how to get one. There is no booking link, no release time, no word on whether it is a ballot or first-come, and no limit per person — only that the tickets are "up for grabs". Anyone wanting to go will need to watch Arts Centre Melbourne, which runs the venue, rather than wait for the government to explain the mechanism.

For 18,000 tickets across four days, that detail is not a small omission. It is the whole difference between a plan and a queue.

What has changed inside

The refurbishment covers lighting and sound, and the government says it brings what it calls the Southern Hemisphere's largest stage up to contemporary standards while keeping the heritage features intact. Work continues on the Theatres Building around it — new eateries and bars, a new stage door, a loading dock and a flexible rehearsal area.

The line most worth pulling out is about access. For the first time, according to the announcement, patrons with mobility challenges will be able to use seating across all three levels. In a building of this age that is a structural change, not a courtesy, and it will matter to people who have spent years being seated wherever the lift happened to reach.

The bigger build

Housewarming is billed as the first major milestone of the $1.7 billion Melbourne Arts Precinct Transformation. The same project covers The Fox: NGV Contemporary, which the government says is set to be Australia's largest gallery of contemporary art, and Laak Boorndap, a new urban garden of 18,000 square metres. The government expects the transformation to create 11,000 jobs over the life of the build. Progress on the wider precinct is tracked at artsprecinct.melbourne.

"This is a project our community has waited for, so it's fantastic that everyone can come and experience it for free," said Nina Taylor, the Member for Albert Park. Karen Quinlan, AM, the Chief Executive Officer of Arts Centre Melbourne, framed it as a beginning rather than an ending: the refurbishment, she said, "means there's a bright future ahead for our beloved theatre to showcase world-class performances".

Six months early is the sort of claim worth remembering in October, when the doors are either open or they are not. On the evidence of the program, the more useful thing to remember is the date — and to be ready when the tickets actually appear.
