The Australian star continues to battle back from injury and organisers have given the former world number 39 a further chance to improve her ranking, which is currently down at 133.
As well the an Australian Open berth. Dellacqua has been given wildcards for the warm-up tournaments in Brisbane and Hobart.
"After missing most of 2010 with a foot injury I have spent this year building on my confidence and match practice," she said. "I now finally feel like I am playing some good tennis and with six Pro Tour event wins under my belt I have the confidence I needed going into the summer.
"I'm really happy with where I am at. I'm hitting the ball well, serving great and doing all the things I should be doing. I feel good and I am looking forward to some tough competition in January.
"It is an amazing opportunity to be able to play the Australian Open, Brisbane and Hobart without having to worry about qualifying and it is really going to set me up for the year ahead.
"It's nice to know my summer is set and hopefully I will get a few more wins and gain even more confidence coming into the Australian Open.
"My goal is to get back into the top 100 next year and then once I'm back inside there, I will reassess."
Teenager James Duckworth will receive a wildcard for the men's draw after impressing with a run to the final of the recent Australian Open play-off tournament.
While Marinko Matosevic won that match to earn his wildcard as of right, the 19-year-old Duckworth has now been awarded one by organisers.
