The Aboriginal inhabitants of the Wyoming area before European settlement were the Kuringgai people.

In 1824 Frederick Augustus Hely (1794–1836) purchased 1,340 acres (5.42 km2) of land adjacent to Narara Reserve.

His mausoleum lies beside the Pacific Highway at Wyoming, close to the family home which was built by his widow.

The grave was designed by architect John Verge and was recently restored after falling into disrepair.

It is at 147 Maidens Brush Road and provides a wide range of services, activities and referrals for the local community.
