Australian serial killer Ivan Milat's great-nephew, Matthew Milat, wants to appeal against the severity of his own 43-year jail sentence for murdering a friend.
Matthew Milat and Cohen Klein, both 19, pleaded guilty in the NSW Supreme Court to murdering David Auchterlonie on his 17th birthday in the Belanglo State Forest on November 20, 2010.
Milat was jailed last month for at least 30 years, with a maximum of 43 years, while Klein was sentenced to a minimum of 22 and a maximum of 32 years.
They have lodged an intention to appeal against the severity of their sentences, a spokeswoman for the Department of Public Prosecutions said today.
The Court of Criminal Appeal will now decide whether to grant them leave to challenge their terms.
In jailing Milat in June, Acting Justice Jane Mathews referred to his "admiration" of the criminality of his great-uncle, Ivan Milat, who was jailed for life in 1996 for murdering seven young backpackers in the same NSW Southern Highlands forest.
Justice Mathews found Klein was an impressionable young man strongly influenced by his co-accused, whom she said planned the murder.
The slaying of Mr Auchterlonie with a double-bladed axe was recorded by Klein on his mobile phone.
The victim's grandmother, Sandra Auchterlonie, said she was shocked Milat would seek an appeal.
"We've started to get back to a bit of normality then he's gone and done this, she told Fairfax.
"They should have both been given life because we have been given a life sentence. I think what they are doing makes them cowards.
