There are grave fears for a Belgian traveller missing in Tasmania for almost two weeks following expert advice the conditions she's presumed lost in are "not survivable".

No one has heard from Céline Cremer since the middle of this month, even after her car was found at Philosopher Falls in the state's remote north-west near Waratah, about 130 kilometres west of Launceston.

Her family at home in Belgium were desperate for any sign of the fun-loving 31-year-old but on Thursday police had confronting news.

Based on expert advice, they said the recent conditions in the remote area were "not survivable for the length of time that Celine is thought to have been exposed in the wilderness".

Police highlighted freezing weather, snow and rain in the region.

Searchers on the ground, in helicopters and using drones had failed to turn up any sign of the missing woman by Thursday.

"At this stage police believe Celine's car has been in the carpark since at least 20 June, and our information indicates she was only equipped for a light day walk," police said.

"The search effort is continuing but we are dealing with extremely dense bushland and the challenging weather conditions are expected to worsen over the coming days.

"We remain in close contact with Celine's family, and our thoughts continue to be with them."

Earlier this week Céline's sister, Amélie Cremer, asked Tasmanians to do anything they could to help find the 31-year-old.

"The most difficult thing is the waiting," Amélie told 9News.com.au. 

"We are helpless here and we just want to know."

Sydney would have a low-rise horizon, the harbour rimmed in red-brick housing, when the Opera House would be opened by Queen Elizabeth II in October 1973.

But even before that moment, the building at Bennelong Point has been close to the affections of Sydneysiders.

It would take close to 15 years from its first proposition to the final pull on the opening plaque lanyard for the Opera House to be realised.

"Even before it was opened, while it's still being built, you start to see the image of the Opera House appearing on international tourism posters," says Scott Hill, curator of a new exhibit at the Museum of Sydney called "The People's House: Sydney Opera House at 50".

As it grew on the harbour, its unique sails taking shape, the political angst over its construction would ebb away as the scaffold was removed, the new white shells gifted the nickname of the "Nuns in a Scrum".

Belying its formal title, there would be a kaleidoscope of differing culture that would be presented from its stages.

Along with what are called the high arts such as theatre and orchestras, that first year of performance would also feature artists as varied as Kamahl and the Bee Gees, along with Les Girls, then one of the raunchiest shows from Kings Cross.

But the Opera House soon created its own wave of kitsch and ephemera, from teaspoons and tea towels, snow globes and key rings, Wedgewood and ashtrays.

"It's the way that people bring the Opera House back home with them, and it becomes a part of their everyday lives," says Scott.

Jade McKellar is chief customer officer at the Opera House.

"I think what makes the Opera House so special," she says, her elbow propped on a pillow printed with its image, "is that combination of the experience, or what you're seeing at the Opera House, with the place, and the building, and the magic in that architecture."

Scott says another important ingredient to the world falling in love with the building, is its location harbourside.

"Out on the promontory, I think is the key to its success."

The exhibit, at the Museum of Sydney in Bridge Street, opens this weekend.

Ozempic, a brand of the popular type 2 diabetes drug semaglutide that has gained popularity online for its use as a weight loss treatment, will remain in shortage in Australia until the end of the year.

The Therapeutic Goods Administration (TGA) said while stockpiles of the drug are improving, the scale of the demand for it means it will be in short supply until at least December 31.

Novo Nordisk, the supplier of Ozempic, is anticipating supply will be steady for the remainder of 2023.

EXPLAINED: Ozempic helps people lose weight. But who should be able to use it?

While the drug has become increasingly popular as a weight loss treatment, the TGA says it should only be prescribed for patients with type 2 diabetes.

"Novo Nordisk and other organisations representing health professionals and patient groups have recommended that prescriptions for Ozempic should continue to be limited to the registered Australian indications," the TGA said.

"Ozempic is indicated for treatment of patients with type 2 diabetes, in conjunction with diet and exercise, when it is not sufficiently controlled with other medicines."

The TGA said limiting Ozempic to diabetes patients is not an attempt to minimise the seriousness of other conditions, like obesity.

"The TGA recognises Ozempic is used to treat other chronic health conditions such as obesity, and that obesity is a serious chronic disease that is challenging to manage," it said.

"Decisions to encourage limiting the use of a medicine to a particular condition during a shortage are difficult, and not intended to imply that other conditions are not important."

Ozempic, which has the side-effect of suppressing appetite, sprung into the public eye as a weight loss treatment following heavy social media promotion.

TikTok, in particular, had a significant amount of content promoting the drug, with videos with the hashtag #ozempic racking up tens of millions of views last year.

A higher-dose version of semaglutide called Wegovy – which is also supplied by Novo Nordisk – was approved in Australia for chronic weight management last year.

However, the TGA said it was still not available in Australia yet.
