“Following inquiries, a 33-year-old man was arrested following a vehicle stop on Rainbow Street, Kingsford, just before 2.30pm today.
“He has been taken to Waverley Police Station. Inquiries continue.”
Earlier this month, Beale was selected as part of a 44-player squad for a Wallabies training camp on the Gold Coast.
The 33-year-old has 95 Wallabies caps and has played for Racing 92 in France in recent years.
In 2014 he was found to have breached the rugby code of conduct by sending an offensive image to former Wallabies business manager Di Patston.
Beale was previously fined $40,000 and suspended indefinitely from play for punching Melbourne Rebels teammates Gareth Delve and Cooper Vuna on the team bus after a Super Rugby game in South Africa.
Beale married his partner Maddi in August 2020 and the couple celebrated the birth of their first child, a boy named Kurtley, last year.
