Proud and Richelle Kadadi, 35, were two months into a relationship and had been at a wedding on the night of the attack, which happened on a street near their Sunnybank home in November 2015.
Defence barrister Mr McGuire told the court Proud had consumed up to nine “beer bongs” and three post-party drinks when he hit Kadadi in the chest and tried to strangle her.
She was rushed to hospital after fleeing and screaming for help.
She spent 33 days in hospital after undergoing an emergency craniotomy and now suffers from post-traumatic stress disorder, depression, fatigue, and memory loss.
The mother-of-one had bleeding on the brain and would have died if she had not received medical assistance.
After an attempted murder charge was dropped due to a lack of evidence, Proud pleaded guilty to the lesser charges of grievous bodily harm and wilful damage.
In handing down his sentence in the Supreme Court today, Justice Tony Moynihan described Proud as a talented AFL player who squandered his opportunities due to alcohol-related incidents.
He said the attack had a “catastrophic” impact on Ms Kadadi.
Ms Kadadi broke down many times today as details of the attack were read out.
She has little memory of what happened.
Proud will be eligible for parole in October 2017.
His brother Johnathon Proud said he is working with his brother on his sobriety.
“[Albert is going to] make a big commitment and I am personally going to be there to help with that,” he said outside court.
“To be honest [it’s a] bit heart breaking to see my brother like that.”
