Australian musician Amy Shark says two stowaways were found hiding in her tour bus as it prepared to cross a border into the UK, describing the discovery as "scary" and "heartbreaking".

Shark said the pair were found in the vehicle's luggage compartment on a trip from Brussels to London.

Both intruders swiftly left the bus after being discovered, Shark tweeted.

She said it had given her crew a scare, but that she felt for those choosing a "dangerous way to chase a new life".

"They didn't threaten us or say a word - they just walked away when found," she told the Australian Broadcasting Corporation on Tuesday.

Shark, whose real name is Amy Louise Billings, is a prominent singer-songwriter in Australia best known for her songs Adore and I Said Hi.

She wrote on Twitter that she had "no idea" how the pair had entered the bus. She did not say where they had exited.

"I didn't think this stuff happened I'm so naive hey," she wrote.

In recent months, the UK has expressed concern over the rising number of migrants , many from Iran and Syria, attempting to cross the English Channel in small boats.
