Few direct international flights and a lack of promotional leadership are among the reasons for WA failing to record tourism spending growth in the past year.
WA's failure to boost international tourism spending in the past year has been partly attributed to a lack of promotional leadership and few direct flights from big markets such as Japan and China.
Figures from a federal government International Visitors' Survey show 8.1 million overseas visitors spent a record $41.3 billion in Australia for the year ending December 2017 - an increase of six per cent on 2016.
WA is the only state to not record growth, which Tourism Council of WA chief executive Evan Hall says is "terrifying".
He noted there was no longer a full-time chief executive or marketing director at Tourism WA since the departmental amalgamations.
"The government's very much made tourism a priority, but we think it's absolutely critical that we bring in a skilled leader to take that organisation forward," he told ABC radio on Wednesday.
Tasmania's 31 per cent growth in international spending was the best of any state and Mr Hall says that is because Tasmania is good at branding itself and it allowed the industry to create attractions like MONA.
"We've got very few new attractions coming through ... it's really letting us down," he said.
"I think a classic example is the stadium rooftop walk, which the last government decided not to do."
Mr Hall said some of the potential experiences WA could create are wave parks, cable cars, zip lines across the river, and hot springs and wellness facilities by the river.
"We have this perpetual problem of saying 'no'," he said.
"We're really offering the same thing that we've been offering for years and we're not keeping up with other states that are creating great experiences."
Tourism Minister Paul Papalia partly blamed the previous government for the figures and said he was "pretty confident that we'll get an uplift" in the next 12 months.
"While we cruised through the boom ... every other state and territory was focused on diversifying the economy through building tourism," he told 6PR radio.
"It takes time to build relationships and achieve new direct flights, which is the key to growing the market from international sources."
Opposition spokeswoman Libby Mettam was critical of the Labor government selling the naming rights to the stadium and removing incentives for international students.
Ms Mettam dodged questions about whether the previous Liberal government's #justanotherdayinWA campaign was a dud, saying it was up to marketing experts to determine whether it had run its course.
