Nonsense Min,they're just tracks from a local foot ball team on a training run.
Seriously, I'm not at all surprised, they're always finding something impressive. I understand Australia is geologically far older than many other places on earth. Eg our local mountains "The Mount Lofty Ranges" are rather low and rounded,indicating great age.Locals call them 'The Adelaide Hills'. The Himalayas one the other hand, are high and sharp,indicating a young mountain range.
