Former millionaire hotelier Andrew Kalajzich will walk free from jail tomorrow having served more than 25 years behind bars for the murder of his wife.

Kalajzich, now 71, was granted release by the State Parole Authority last month and it has just been announced he will be released from Silverwater prison tomorrow.

He is expected to be welcomed into the lives of his now-adult children and the rest of his family, who have supported him despite the convictions, the appeals and a judicial inquiry.

The Parole Authority decided to release Kalajzich, convicted of murder and conspiracy to murder of his wife Megan, following the expiration of his 25-year non-parole period in December last year.

The Serious Offenders Review Council found that he had been a model prisoner, demonstrating excellent progress in education programs and a strong employment history while in jail.

The council, along with the Probation and Parole Service, supported his release.

No submissions from members of the public or other interested parties were received by the parole authority in challenge to the expressed intention to release the former Manly identity.

Kalajzich rose from working in his parents' fish and chip shop to become a respected businessman, building and owning the then Manly Pacific International Hotel in the 1970s.

But he was convicted of his wife's contract murder, a jury finding he paid hitman Bill Vandenberg $20,000 to shoot his wife.

He has always denied any involvement in the crime and is expected to continue to maintain his innocence.

Kalazjich maintains somebody broke into his home and shot his wife twice in the head while she slept, saying he had rolled off the bed and escaped injury.

Both a Court of Criminal appeal challenge and a 1995 judicial inquiry by retired Supreme Court judge John Slattery, QC, failed to overturn the conviction, the latter ultimately finding "there are no doubts or questions about the guilt of the petitioner".

A family spokewoman, Pippa Kay, told the Herald Kalajzich was "just looking forward to getting back to his family and people that love him".

Kalajzich made subsequent attempts to have his sentence reduced, and in 2005 was reported to have written to the state government offering to donate his kidney if he was let out early.

The then attorney-general Bob Debus rejected the offer.
