The latest round will be for a $100 voucher for use on participating CBD and North Adelaide Hotel or a $50 voucher for use across suburban and regional SA.

It will also offer special ‘mid-week’ deals at some CBD venues in a bid to attract more visitors to the city during the week.

Open to Australians living in any state, the online ballot will open at  southaustralia.com/voucher at 9am Friday and closes 5pm on Tuesday, June 1.

Applicants will be notified on Wednesday, June 2, whether they have been successful or not, and can book from 2 June to 30 June, for travel from 2 June to 31 August 2021 (excluding Saturday nights).

The first Great State Voucher scheme opened in January with further schemes in March and April.

While tourism operators in many regional areas are experiencing boom times, CBD hotels have generally struggled since the coronavirus pandemic.

Premier Steven Marshall said round four of the Great State Voucher Scheme would be a much-needed shot-in-the-arm for our CBD hotels, pubs, clubs and restaurants and businesses, helping to create and sustain jobs across the entire state.

“We’ve seen the data – during the travel period of the last round of accommodation vouchers, regional South Australia had its best occupancy rates for a three-month period ever recorded and CBD hotels hit the highest occupancy of any mainland Australian city,” Premier Marshall said.

“These vouchers stimulate travel, they get South Australians and interstate visitors booking overnight stays in our great state, and they sustain and create jobs in our visitor economy.”
