Thankfully, all four grand slams now offer equal pay for both men and women. But this is still highly contestable. Many people would argue that equal pay should only be based on comparable sports - for example, cricket or soccer where the same minutes and overs are played.

This can argument is often disputed by referencing sports like athletics. You would think based on this argument that marathon runners should be paid more than 100-metre sprinters. Doesn't happen.

Women's FIFA World Cup was an outstanding display of female talent and endurance. They play the same minutes as men, they draw crowds as do the men, and they train as hard and as often as men. So, as the US team would say, where's the equal pay?

Back to tennis, and it's only the grand slams where men play two more sets than the women. There are more than 60 ATP events where both sexes play best of three sets. Yet, if you look at the Rogers Cup the female winner took home $500,000 and the male a cheque for $1 million.

There were no female athletes in Forbe's international list of the highest paid athletes for 2018. The Australian netball team raised the issue of equality in recent years as well, demanding a fair go.

For women in sport, publicity through televising games will attract greater sponsorship. Take your mind back to the early 2000s when Anna Kournikova was one athlete with the highest income, but she never won a singles tennis tournament but always made the television screens. Our female athletes should be treated with the same respect as their male counterparts and decisions on broadcasting and pay based on performance, not looks or attitude.
