They lead retail empires and technology powerhouses. They employ thousands of Australians and inspire countless others. They are hardworking, dedicated and passionate.

They are Australia’s top female entrepreneurs.

Each year our friends over at SmartCompany publishes its list of top female entrepreneurs to coincide with International Women’s Day.

This year’s list features several exciting new faces, including Envato co-founder Cyan Ta’eed and fitness entrepreneur Michelle Bridges, as well as women who have long been at the forefront of Australia’s business community – and who continue to inspire.

SmartCompany’s annual list of top female entrepreneurs is ranked according to the revenue of their business.

In 2016, the combined revenue of the businesses on the full list of 30 is $10.67 billion, up $200,000 from last year.

Wherever possible, revenue figures have been provided by the entrepreneurs themselves.

If not, SmartCompany has relied on publicly available sources, industry contacts or internal estimates. An asterisk shows when revenue has been estimated.

Below is the top 10 from SmartCompany’s list of 30 top female entrepreneurs for 2016:

1. Katie Page

Company: Harvey Norman

Established:1982

Revenue: $2.71 billion (with Gerry Harvey)

Katie Page began working as an assistant at Harvey Norman in 1983 and has been chief executive since 1999 of a company with almost 200 stores in Australia and 86 stores overseas. Harvey Norman Holdings encompasses stores and franchise of Harvey Norman, as well as furniture brands Domayne and Joyce Mayne.

Harvey Norman’s revenue of $2.71 billion for 2014-15 comes from company operated sales revenue (not including franchises), as well as other venue and income items. The ASX-listed company, which is controlled by Page and husband Gerry Harvey, also has an estimated $2.32 billion in property portfolios.

Harvey has previously referred to Page as “the mastermind behind it all” in media interviews. Page is also a director at The Retail Council and the Trustee of the Sydney Cricket and Sports Ground Trust. Page also recently signed Harvey Norman as naming right sponsors for the first all-female Bathurst 1000 entry since 1998.

2. Gina Rinehart

Company: Hancock Prospecting

Established:1955

Revenue:$2.04 billion

Mining magnate Gina Rinehart has slipped to second place in SmartCompany’s list of top female entrepreneurs, after previously hanging on to first place on the annual list since 2012.

Mining had a tough year in 2015 and Hancock Prospecting did not escape impact. Weak commodity prices have contributed to revenue slipping more than 22% to $2.04 billion in 2014-15 according to Business News. Although there was a 14% increase in shipments at the half-owned Hope Downs mine, the fall in iron ore directly impacted on profits.

Much has changed in the past year as Rinehart is no longer Australia’s richest person, having been unseated by reclusive American heiress and Australian resident Blair Parry-Oaken on Forbes’ annual Rich List. Rinehart’s personal net worth is estimated byForbes’ to be $9.4 billion.

3. Vicky Teoh

TPG recorded a 31% increase in revenue, from $970 million to $1.27 billion, in the 2014-15 financial year. The biggest gains for TPG have been taking acquisition of internet provider iiNet Group in September. Now combined, the telcos provide broadband services to over 1.8 million subscribers and we’ll be watching closely how this impacts on TPG’s revenue in the next six months. TPG also recently stuck a dual agreement with Vodafone, including a major dark fibre transmission network expansion and migration of TPG’s mobile customer base to the Vodafone network.
