Premium Content North Mackay Athletics Club members Lexie and Billy-Anne Sievers are the perfect twin tandem. One excels on the track and the other in the field; each providing a benchmark and motivation for the other. In just their first year of athletics, the nine-year-old Northview State School students quickly showed they have an aptitude for the sport. Hailing from a hip-hop and touch football background, Billy-Anne and Lexie combined for 29 and 21 personal best times respectively in just under half a season at NMLA. Billy-Anne s tally topped all junior girls at the club, crowning her the Most Improved Female Athlete of the Year.
