Prince Harry may consider leaving Australia if the media interest in him there does not diminish, Clarence House has said.
Prince Harry is thought to be planning a career in the military
The prince travelled to Australia on Tuesday and is meant to be spending part of his gap year working as a farm hand or "jackaroo" on a farm in the outback.
But a spokeswoman for the prince said the Australian media were being "quite intrusive" and have "surrounded the place".
She said he cannot move around and learn the trade he intended to.
The spokeswoman said he needed some space in order to acquire these new skills and if the interest continued the prince might have to review his options.
Harry was intending to stay for three months in Australia, spending much of his time rounding up cattle and sheep.
He was set to work from dawn to dusk for less than £100 a week on remote cattle and sheep stations in the outback.
On arrival in Sydney, Harry posed for the cameras at a zoo, but his entourage hoped media interest would then tail off.
After his gap year, the prince, who gained B and D grade A-levels at Eton, plans to join the military.
He plans to apply to Sandhurst military academy where the UK's top Army officers are trained. The institution is also occasionally attended by the children of foreign heads of state.
The trip has already caused controversy with criticism of the estimated £600,000 cost for the 12-strong squad needed to protect the prince.
