AQUANITA EIGHT BANNED OVER BIGGEST SCANDAL IN AUSTRALIAN RACING HISTORY

WHAT DID THEY DO?

Five trainers and three stable employees, all connected to management company Aquanita Racing, administered race day treatments or "top-ups" of bi-carb and tripart paste to horses for more than 100 races over seven years.

Sodium bicarbonate buffers the build-up of lactic acid so helps the horse run longer rather than faster.

HOW DID IT UNFOLD?

Aquanita float driver Greg Nelligan was "caught red handed" inserting a syringe in Robert Smerdon-trained Lovani's mouth on Turnbull Stakes Day last October.

Stewards downloaded more than 70,000 text messages from his mobile phone - about 1000 texts over seven years put in evidence.
