Lawyers for the estate of late mining magnate Michael Wright – who are appealing against the record $25m payout handed to his secret daughter Olivia Mead – have said again that the teenager’s extraordinary ‘wishlist’ revealed in court was “not grounded in reality”.

It is almost two years year since the sensational multi-million dollar award to the PR student, who revealed herself during her courtroom battle with her half-sisters for a larger slice of her father's massive fortune.

The appeal against the momentous award of $25 million to the teenager was being heard in the WA Court of Appeal today, with the legal team for the executor of the estimated billion dollar Wright estate claiming that the award was too much, and had no legal basis.

And in arguments with the three-judge appeal panel hearing the appeal, Jane Needham SC pointed to the list of items Ms Mead told the court she might require in her lifetime – which included a crystal studded grand piano, the most expensive bass guitar in the world, and 300 pairs of shoes a year for life.

The Wrights are saying that the $3m that was left for Ms Mead in the will was enough to provide for a $1m house and an income for life.

Ms Mead has already been given $3m from the will – but is battling to retain the rest of the fortune granted by Master Craig Sanderson – which is currently held in trust.

Justice Michael Buss, president of the Court Appeal said in court today, that the list used during the trial was “just silly”.

And he also raised the issue of whether granting the enormous sum of money to one so young was appropriate – suggesting that there might be scope to place any more money that is awarded be held in trust until Ms Mead turned 30 years old.

“What might seem a good idea now might not seem such a good idea in 10 years,” Justice Buss said,

Mr Wright's father Peter was a business partner of mining magnate Gina Rinehart's father Lang Hancock.

During the trial, Ms Mead’s initial “wishlist” came in at about $20m, but was revised down to around $12.5m by the end of the trial.

Ms Needham said that there was no argument by the Wright family that the award from the estate should provide for “bread and butter”, saying given the size of the estate, Ms Mead should also get the “jam and cheese”.

But she said $3m was more than enough for that purpose.

“As a quantum, that is adequate to provide a house and an income for life,” Ms Needham said.

“What we say is wrong is ... for the (court) to say because it is such a big estate I will give her more than double what she said she needed.”
