Actor James Millar hopefully already said his goodbyes and packed up his things from his family home in Kenthurst before he went to Perth recently, because by the time he gets back the April 8 auction will have passed and - fingers crossed - someone will have paid $4.25 million to $4.65 million for the resort-style estate.

Millar, who is touring with Tim Minchin's Matilda the Musical playing Miss Trunchbull (for which he won a Helpmann award last year), has called the Kenthurst property home since 1982 when he was two and his parents Graham and Gaye purchased the 2.17-hectare property for $90,000.

And it's been his home in Sydney ever since. Known as Sandalwood Park, the five-bedroom residence comes with a heated pool, a billiard room, spa, tennis court and guest quarters.

The Millars are off to the northern beaches, prompting the listing with Will Hampson and Kate Lumby, of Lumby Hampson.

Best in the valley

JP Morgan's managing director Andrew Best is set to off-load his Kangaroo Valley retreat, Baltard II, for more than $4 million.

At that level the sale might almost match the $4.3 million the state government has paid JP Morgan for financial advice on the proposed sale of the land titles registry.

Speaking of which, those same public records show Best, a long-time Centennial Park local with his wife Natalie, paid $1.8 million for the 38 hectares in 2006.

The lavishly appointed weekender with tennis court and pool is listed with Belle Property Berry's Nick and Gary Dale.

On song in Enmore

Opera singer John Wegner and his wife Mignon have sold their Enmore Victorian terrace for a smidge over $2 million.

The four-time Helpmann award winner and former principal artist at Opera Australia retired due to Parkinson's disease.

The three-bedroom house last traded in 1994 for $300,000, and was beautifully renovated before it was sold by Tina O'Connor, of Ray White Annandale.

Woollahra to Prague

Philanthropist, former publisher and art collector Tom Schrecker has long split his time between his homes in Sydney, London, Prague and Val D'Isere, but having now settled permanently in the Czech Republic he is selling his long-held Woollahra base.

The three-bedroom penthouse has not traded since 1978 when it was sold for $115,000 by fur merchant Telian Goldberg and his wife Kety.

Schreck was one of the 669 Jewish children rescued from Prague before the Nazi invasion of 1939 by Sir Nicholas Winton, who later moved to Australia and became Asia Pacific director of Readers Digest.

Harriet France, of Sotheby's International, is asking $2 million.

Making tracks

High-profile barrister Nancy Mikhaiel is offloading her former Victorian-era home in Randwick now she's ensconced in her $8.5 million beachside home nearby.

Given its position on Alison Road opposite Randwick Racecourse, the house is fittingly named Shahzada after the purebred Arabian stallion that was imported from England to Australia in 1925.

Mikhaiel, whose clients have included jailed former MP Eddie Obeid and broadcaster Alan Jones, purchased the 500-square-metre property in 2009 for $2.1 million.

Seaton Jones and Peter Taylor, of Ray White TaylorJones, are asking $3.3 million to $3.5 million ahead of the April 8 auction.

Fundie lists in Birchgrove

Fund manager James Simpson has not long completed a renovation of his waterfront residence in Birchgrove and has it up for sale with a $7 million guide and an April 4 auction.

Simpson is off to Mosman and the $11 million house he purchased in early 2015 from Nicolette Pappas, wife of NAB senior executive and Gina Rinehart's preferred banker Spiro Pappas. Incidentally, the Pappas clan have since taken to North Bondi, where they paid $8.55 million two years ago.

Simpson paid a bullish $7.2 million for his Birchgrove property in 2007 from lawyer Susan Hilliard and her partner, former PowerTel chief Shane Allan.

It is now listed with Robert Page and Cae Thomas, of Black Diamondz Concierge.
