The off-spinner also said that the slow Sydney wicket did not allow him to bring the secret delivery during the drawn third Test.

"This summer has been challenging with obviously playing against India again. They have come up with plans to combat me. But to be honest I am quite happy with the way I have been bowling. I have been able to create some chances which has been really positive...but some days the wheel doesn't turn around and you don't have much luck in the middle," said Lyon while speaking to the media in a virtual interaction on Wednesday.

"I am very happy the way they are coming out of hand and I am confident and excited to get here at Gabba where there will be a bit more bounce than what was at the MCG and SCG, definitely SCG anyway. I am excited that if I keep doing my job then luck will keep changing here and there. I just got to stay patient...Who knows I could bring (secret delivery) on Day 5 if we happen to be bowling. It is still coming...keep watching."

About the Sydney wicket, he said, "It would have been nice to have a big footmark...but I was still able to get spin here and there out of it. The wicket was a bit slow and we couldn't capitalise on our chances."

The 33-year-old added that he is far from done and is hungry for more matches. He wants to continue playing for well beyond 100 Test matches.

"When I finish my career, I will be able to sit down with smile on my face -- sort of gave my all. This is my 100th. But I am far from being done in my eyes. I am more hungry than ever. I want to go and play as much cricket for Australia and win more matches," he said.

"(But) not look too far ahead and try and take each and every day with a smile on your face. Mike Hussey gave me that piece of advice before I bowled my first ball. He said, come up and play with a smile on your face, you will hopefully relax a bit. Punter (Ricky Ponting) said in the first game 'just back your skill'.

"There have been some highs and lows. You look at the Adelaide Test in 2014, that was one of the biggest highs in my career and then you look at Edgbaston, amazing high, you come to Leeds, you come down the ladder, so that is something amazing about Test cricket. It is amazing ride. There have been lots of ups and down in my career," Lyon added.

The off-spinner said that he would be talking to his personal spin coach John Davison, who is currently with Sydney Thunder in the Big Bash. The bio-secure environment hasn't allowed Lyon to see him during the ongoing series. But Lyon says he will speak to him like he does after every match.

"I will contact him anyway. I usually contact him after every Test and have a conversation. He is the best spin coach at the moment. I will touch base with him and nail down a couple of little things -- regarding the pitch, need to adapt," he said before adding that he is being ably guided by team captain Tim Paine and batsman Steve Smith.

"I think I have played enough cricket to know what I need to do. That is the beauty of having Tim Paine and Steve Smith around the bat there as well. Obviously, they are very talented. They have passed a lot of knowledge from when Smith was batting against (Ravichandran) Ashwin to Paine keeping against me."

Lyon will become the 13th Australian to play 100 Test matches. He joins an elite league that comprises Ricky Ponting, Steve Waugh, Allan Border, Shane Warne, Glenn McGrath among others. Lyon says he still can't believe it.

"It has been very exciting because I look at the 12 guys to have played 100 Test matches. They are pure legends in my eyes not just for CA but all around the world. I am going to pinch myself each and every day to see my name against those fellows. It is pretty amazing," he said.
