According to Mansion Global, the property, known as Lodge Dauphin, is owned by Linda Penn, chief executive officer and co-owner of Australian menswear giant Lowes, and her orthodontist husband, David Penn.
The couple purchased the Whale Beach property for $3.075 million in 2012 before transforming it into a luxury estate.

Built from more than 1,000 tons of local sandstone, the five-bedroom, five-bathroom mansion spans three levels and features multiple living spaces with high cathedral ceilings, marble fireplaces, and panoramic ocean views.
The Penns engaged architect Michael Suttor to create the sandstone mansion, with designer Deanne Rooz handling the sophisticated interiors.

Renowned landscapers Richard Unsworth and Paul Bangay designed the extensive grounds, which include tiered native gardens, manicured edges, and the standout feature, a private 18-hole golf course.
“It is an incredible property, with almost 2,200 square meters of land on the oceanfront with a small golf course inspired by the St. Andrews golf course in the U.K.,” selling agent David Edwards of LJ Hooker Palm Beach told Mansion Global.

According to the listing, the estate functions like a self-contained resort, featuring a sauna, spa, and infinity pool overlooking the Pacific Ocean.
The main living level includes a combined lounge and dining area with high ceilings and a marble fireplace, while the contemporary kitchen boasts high-end appliances, including Sub-Zero refrigeration and a Wolf oven.

The primary bedroom suite includes a palatial open-plan bathroom with a bespoke freestanding bathtub, dual vanity basins, and a walk-in wardrobe.
For guests or staff, a self-contained studio with a kitchenette and separate entry is available on the main level.

Additional luxury amenities include a large gym or games area with a bar, wine cellar, heated infinity pool, egg-shaped spa, and poolside lounge.
The property also features smart lighting, zoned air conditioning, Vintec air filtration, 30 security cameras, a Sonos sound system, and an elevator to all levels.

Mr Edwards said that the Penns are selling because they’re spending more time at their French Riviera property.
The listing is expected to set a new price benchmark for Whale Beach, which has historically seen properties tightly held across generations.
