Meet Laurie Slater, the oldest competitor in this year's National Sheep Dog Trials.
And, despite relying on a mobility scooter to get around, the 88-year-old sheep farmer has now reached the finals.
Mr Slater, from Murrumbateman near Canberra, is no stranger to the event — he took out the championship in 2014.
The trials take place over a week in the rural village of Hall in the ACT. A record 358 animals are competing to be this year's top dog.
Eight years after he won the competition, Mr Slater said he was determined to give his 13-year-old dog Jules another shot.
So far, she has taken it.
To win the coveted Duke of Gloucester sash, a dog must shepherd three sheep through an obstacle course into a pen, losing as few points as possible.
Each dog starts with 100 points and 15 minutes and loses points if the sheep wander from where they should be or for other "misdemeanours", such as barking.
Mr Slater had almost decided against competing this year, but competition president Sarah Srydych opted to allow his late entry.
"Laurie came to me two days ago, and … said to me 'Sarah, I want to have a run'.
"The rules are here that you cannot enter a dog after the competition entries are closed — but this is Laurie we're talking about.
"Laurie's helped so many people. He's been competing for so many years. So I said to Laurie, 'Yes, let's do it'.
Mr Slater's score put him and Jules among the top 20 entrants, qualifying them for today's finals.
The event, now almost 80 years old, began during World War II to raise money for the families of military personnel.
"It started in 1943 on Manuka Oval [in central Canberra], can you imagine?" Ms Srydych said.
"We had more than 300 dogs on the ground."
She said that, over the years, the trials had also helped build bonds between people in the cities and the regions.
"To me, the importance of this, and attracting the spectators, is to keep this Australian sport alive."
