The event will bring together more than 130 travel sellers, including inbound tour operators, airlines and established Australian tourism businesses, with about 100 buyers.
It will cater to specific markets and segments such as youth travel, premium experiences, and wildlife and adventure travel.
Australia Marketplace UK and Europe will be held annually over two days during the last week of October in central London, with a gala event at Australia House.
Dates for the 2019 event and venue details will be announced in May.
Sally Cope, Tourism Australia regional manager UK and northern Europe, said the new Australia Marketplace would highlight the best of what Australia has to offer.
“With visitor numbers from the UK and wider Europe at near record levels, it is the right time to launch this event and build on current momentum,” she said.
“The UK remains one of Australia’s largest tourism markets and continues to show resilience in the face of current local uncertainty.
"Tourism Australia sees this as a key moment to work closely with the travel trade to create new and lasting opportunities for visitation from this market.
“The UK trade has remained highly engaged with Australian industry partners and the new Australia Marketplace, alongside our Aussie Specialist Training Programme, and will allow these strong ties to continue to flourish."
