Coetzee, who came under huge pressure after the Springboks lost eight of their 12 tests in 2016, was particularly pleased with the response of his team after they went 20-10 down in the 48th minute.
"I thought the referee was too slow to penalise the Wallabies for playing Bok jumpers in the air, especially in the second half when the Boks got their driving maul going".
What an effort from Kurtley Beale!
'Missed opportunity there, ' said Australia captain Michael Hooper. Re-start wasn't up to scratch again but plenty to like there as well'.
It came far earlier than the rookie expected, prepared for an injection in the final 20 minutes, with little time to comprehend the moment when it actually came in the 18th minute.
The Wallabies flew to Canberra on Sunday afternoon, ahead of Saturday's clash with Argentina.
The lead was short-lived: Israel Folau won back Australia's restart, and Beale produced a dodge-and-weave run to touch down for a try.
Sanchez scored Argentina's only try right on halftime to complete a rare first-half "full house" - scoring a try, conversion, penalty and drop goal in the opening 40 minutes - to grab a shock 19-15 lead. Uelese made an early break, and Polota-Nau returned to the field after Kriel's try.
Coach Michael Cheika said both the scrum and the lineout needed attention this week.
The draw extended their unbeaten run to six matches this season and a victory over the world champions at the North Harbour stadium next week could send them top of the Rugby Championship standings with two home matches remaining.
Allister Coetzee's side were humiliated twice past year by the All Blacks, losing 41-13 in Christchurch before they were thumped 57-15 in Cape Town as Hansen's team ran in nine tries.
"This team now has got great character and culture and that's what wins trophies". "We've seen the last couple of weeks how physical they've been, especially up front".
"Argentina love to scrum, it's the foundation of any good side and we'll have to better than we were last weekend and definitely lineout-wise we were pretty scratchy as well, so we've got a bit of work to do".
Cape Town - Former Springbok coach Nick Mallett has criticised the officiating of New Zealand referee Glen Jackson during South Africa's 23-all draw with Australia in Perth on Saturday.
