Ivor Evans was just 14 years old when he won an Australian national flag competition in 1901.
Four other people - all with similar designs - also shared the 200-pounds prize money.
118 years later his proud great-grandson was horrified when he saw neo-Nazis saluting the Australian flag at a weekend rally in St Kilda.
Matthew Evans says a flag is not just a bit of cloth, but a symbol of so much more.
Matthew's ancestors also set up the Evan Evans flag company in 1877 - and now the 21-year-old is back living in the goldfields region.
Matthew says he believes indigenous people are included in the existing Australian flag through the use of the Southern Cross, whose stars feature in aboriginal astronomy.
In 2018 the International Astronomical Union announced it would give the smallest star Epsilon the new official name of 'Ginan', which is the name the Wardaman people of the Northern Territory have known it by for thousands of years.
