A registered sex offender who allegedly fled Australia in his yacht is set to front court today after being arrested by Thai authorities.

Federal police charged the 57-year-old after he arrived at Perth Airport following his deportation from Thailand last week.

He arrived in court on May 10, where he remains in custody.

Authorities allege that the North Queensland man breached his travel reporting obligations after leaving the country without notifying Queensland Police in October last year.

He was arrested by Thai authorities in April before being deported back to Australia.

The 57-year-old was charged with one count of restrictions on overseas travel by certain registered offenders and could face up to five years behind bars.

AFP Acting Superintendent Peter Brindal said federal police work closely with international law enforcement to bring alleged criminals to justice.

"The seamless and collaborative relationships with law enforcement partners in Australia and across the globe is critical to combating criminal activity and keeping our communities safe," Brindal said.

Australians are currently sitting on more than $2.7 billion in lost or unclaimed money.

The Australian Securities and Investments Commission (ASIC) is urging people to spend a few minutes checking if they are eligible for a portion of the cash.

The sum includes money owing from old bank accounts, shares or insurance policies.

The money is often lost because people lose contact with financial institutions or investment companies after moving house, changing their name or simply forgetting about an account over time.

In some cases, the money has remained unclaimed for decades, with records dating back to the 1950s.

The single biggest amount still unclaimed is $1.3 million.

To check for unclaimed money, people can simply type their name into ASIC's MoneySmart website.

There is no deadline for Australians to make a claim, which means people can search and claim at any time.

In 1995, mathematician Jim Miekka coined a phrase for an economic indicator that could signal a recession.

Named for the doomed zeppelin, the Hindenburg Omen is supposedly triggered right before a stock market crash.

And on the New York Stock Exchange and the Nasdaq overnight on Friday, the Hindenburg Omen was triggered simultaneously.

The indicator is when one side of the stock market is soaring while others are at record lows, AMP Economist My Bui told nine.com.au.

"If the economy is running well, then most of the components, or most of the stocks that are making up the index should actually all go up," Bui said.

"Else it might not be a sustainable rise."

Right now AI companies and other technology businesses are doing incredibly well on Wall Street.

Meanwhile, health care and telecommunications are struggling.

Right now the US share market is surging while consumer confidence is at a record low – a trend economists don't believe to be sustainable.

But the Hindenburg Omen is far from a guaranteed indicator of a looming crash.

While it has predicted just about every Wall Street crash in the past few decades, it has also forecast dozens more crashes that never happened.

The omen would have been triggered 69 times since 1965 – and there have not been 69 stock market crashes since then.

Brokers have been unfazed by the omen being triggered this time around.

The S&P 500 Index hit a new record high overnight, up nearly 57 points.

So what are the chances of a stock market crash?

"It's never zero, and I do think it's higher than the historical average," Bui said.

"But I think that if there's a big decline in shares, like, say, 10 per cent or more, then Trump would do something substantial to boost it up again."

The ASX200 has followed Wall Street up this morning.

Multimillionaire Boost Juice founder Janine Allis has criticised the federal budget's tax changes, saying they are "just so unfair".

In a social media video, the typically apolitical Allis said Labor's decision to wind back the capital gains tax discount and grandfather negative gearing would "destroy the core of what Australians are".

"I would put my house on the line, I put everything on the line, and then I work my absolute butt off, risk everything, be away from my family, etc," she said.

"To eventually make a profit and give nearly half to the government?

"Oh my god, that is just so unfair. It doesn't allow you to get ahead, it doesn't inspire you to actually take the risks that you need to take."

The government broke an election promise by moving to replace the capital gains tax discount with a less generous inflation-linked rate and a minimum 30 per cent rate.

Negative gearing will be limited to new builds and no longer apply to any existing properties bought after 7.30pm on May 12.

Both policies are commonly used for property, but the capital gains tax discount can apply to most capital assets, like managed funds, while negative gearing can apply to other income-producing assets like shares.

Allis said she believed the changes would kill ambition to start a business and ward off investment from global businesses.

"If you tell people on election that you're not going to be touching their negative gearing and capital gains tax, you have to stick with it," she said.

"The reason being is people make decisions in business based on what you tell them. If you don't tell the truth or change your mind, it's too big of a decision.

"I might have misunderstood it, I hope I have, it's not passed but if it does, the unintended consequences of this is horrific." 

Allis is one of the country's most successful self-made entrepreneurs after founding the Boost Juice chain in 2000.

It went on to become a global empire with more than 850 stores across the world.

Allis is the part-owner of Retail Zoo, which is the holding company for Boost Juice, Betty's Burgers and Salsas Fresh Mex.

A vote in the US House of Representatives that would have forced Donald Trump to immediately end America's war with Iran has ended in a tie.

Three Republicans crossed the aisle to vote with 209 Democrats on a resolution directing the president "to remove the United States Armed Forces from hostilities against the Islamic Republic of Iran".

One Democrat and an independent joined the remaining 210 Republicans to vote no.

A tied vote in the House means the resolution did not pass.

The three House Republicans who crossed the floor this morning are all facing tight re-election races in November's looming elections.

Earlier this week, Trump lost the support of another Republican in the Senate.

Lisa Murkowski voted against the war for the first time, alongside two other Republican opponents.

Her switch meant legislation to end the war in the upper house failed by two votes.

If the resolution passed both houses, Trump would have no choice but to end the US blockade of the Strait of Hormuz and cease all hostilities with Iran.

The handful of defecting Republicans in a narrowly held Congress should be cause for concern for Trump.

In previous wars, Congress had a habit of rallying around the flag to support it. 

The declaration of war on Japan in 1941 passed the House 388 to one, and in the Senate 82 to zero.

The vote was held an hour after President Franklin Roosevelt's "day that will live in infamy" speech.

But Trump has done very little to convince the American people of the value of the war with Iran.

Democrats are tearing into Trump over the war and its cost.

"It's been 76 days since Trump launched his illegal war in Iran, and the Administration is still refusing to share with Congress or the public an official legal rationale for the conflict—all while pushing for $US1.5 trillion ($A2.08 trillion) for the Pentagon," Senator Tim Kaine said. 

"Everything about that is ridiculous."

Congresswoman Pramila Jayapal described the war as "senseless".

"Billions of taxpayer dollars wasted. Thousands of lives lost. Soaring energy prices," she said.

"That's what Republicans just voted for."

While the president is the commander-in-chief of the US military, only Congress has the authority to declare war.

They also have the power to fund the war, which has cost the Pentagon an estimated A$40 billion so far.

Because Congress did not authorise the war, the costs of it are being pulled from the general Pentagon budget.

The Wall Street Journal reported today that the Pentagon will have to cancel training exercises and other spending because so much money is being diverted to the war with Iran.
