With regular central defensive pair Steven Taylor and Fabricio Coloccini out with respective groin and hamstring injuries over the past month, Good said Newcastle manager Alan Pardew was ready to pick him in the Premier League when he was struck down by a fitness concern of his own.
The 20-year-old central defender, who joined Newcastle from Melbourne Heart at the start of last season, missed out on an opportunity to wear the black and white stripes due to a hamstring strain.
"It was only a relatively minor injury but the timing couldn't have been worse because of the injuries and suspensions," Good told the Herald Sun.
"He (Pardew) always talks to the youngsters and he said if I was fit I would've been given opportunities in last few weeks, which is a no-brainer.
"Two centre-halves were injured and one (Mapou Yanga-Mbiwa) suspended."
As he sat on the sidelines, Good watched 22-year-old Paul Dummett and 20-year-old Massadio Haidara make rare appearances in Newcastle's back four.
But with that young pair now injured and Taylor and Coloccini still week-by-week prospects as they continue to recover, Good believes he is not far away from earning a call-up to the first team.
Good played 25 matches in his only season with Heart in the A-League, while he made 12 appearances while on loan with League One club Bradford City last season.
Highlights of Good's stint in the English third division included 90 minutes in both legs of their shock 4-3 aggregate win in the League Cup semi-finals, plus 45 minutes in the final against Swansea.
The experience with Bradford has given Good confidence he is ready to take the next step in England.
"The first year was tough getting used to training but I feel a lot more comfortable now," the Melburnian said.
"I guess it's the same in any environment.
"But I had experience last year in some big games which helps, I've just got to get my body right."
