Private equity, corporate finance, investments, equities


Wilbow is an active investor in both listed and unlisted equity and debt markets. We hold and manage a diversified portfolio of equity and debt positions and possess broad experience in the provision of debt and/or equity solutions to businesses.

Wilbow’s focus in listed markets is to identify companies, in Australia and internationally, with valuations that do not reflect growth potential.

Unlisted investment opportunities ideally have the following characteristics:

  • Our capital has a clear purpose – to facilitate and accelerate growth or be part of a capital solution
  • Experienced and aligned management of high integrity
  • Profitable underlying business or a clear path to profitability with an attractive business model
  • Scope for Wilbow to contribute to the direction of business either through formal board roles or informal engagement with management
  • Potential for attractive investment returns over flexible time frames
  • A broad range of industry sectors will be considered

We aim to be flexible in our approach to all equity and debt investment opportunities and work to provide the most aligned solutions possible.

The collection continues to grow and contains a diverse range of styles and periods which include paintings, photographs, works on print and sculpture. Work by artists such as Fred Williams, Arthur Streeton, John Russell, Ian Fairweather, Peter Booth and Bill Henson.

Wilbow Group is a benefactor of art through donations (including works of art) and sponsorships of various exhibitions. The collection has been publicly exhibited and elements of it are lent regularly for exhibitions. Wilbow has been a long term supporter of institutions such as the National Gallery of Victoria, Monash Gallery of Art, Benalla Art Gallery, Heide Museum of Modern Art and has donated art to National Gallery of Art, Canberra.


William D Bowness founded Wilbow Corporation in 1976, which grew to be one of Australia’s largest privately owned property development companies, with interests in Melbourne, Brisbane, Dallas (USA) and Auckland (NZ). Wilbow Corporation undertook a broad range of developments, including residential subdivisions, medium density housing, high density apartments, retail shopping centres, commercial office buildings, industrial office parks and retirement facilities. The success of the Wilbow business and high regard it was held in was demonstrated by the numerous development industry awards its projects received. The Australian interests were sold to a major public company in 2006 and the NZ office closed in 2005. Wilbow’s USA property operations have been retained.

Following the sale of the Australian interests, Wilbow Group was formed to be an investment company that focuses on its USA property interests, private equity, listed equities and property development funding. Philanthropy and the arts continue to be an important part of the Wilbow philosophy.
