The 30-year-old left-hander has previously played seven Tests for Australia where he scored a century on debut against Sri Lanka in 2011 but averaged just over 27 and was dropped following a horror series against India in Australia during the 2011-12 summer.
Things haven’t gone to plan for Marsh since then with a run of hamstring injuries as well as some off-field dramas, but he has got himself back on track in terms of his body and form now to be in contention for further national duties.
That sees him now about to head to England as part of Australia's limited overs teams, but after strong Australian A form recently in South Africa, Marsh is right back in the hunt for the troublesome No. 3 spot in the Test team.
With Phil Hughes, Ed Cowan and Usman Khawaja all failing to secure that No. 3 position in the current Ashes series in the UK, Marsh sees a spot there for him for the return series in Australia this summer and feels ready to grab that opportunity with both hands if it presents.
"I'm sure there will be opportunities for players in that Test team. The start of the Shield season is going to be really important and I guess whoever is scoring runs at the right time is going to get an opportunity. We'll just have to wait and see what happens," Marsh said.
"I feel like I'm in a pretty good head space at the moment with my game and I just have to put the runs on the board now to get that opportunity again. I feel like if I do get that opportunity again I feel like I will be a lot more ready to go this time around.
"It's obviously a really tough place to bat and it has been challenging for the Australian team over the last two years to try and fill that No. 3 spot. There are plenty of good young players around Australia who can put their hands up to secure that spot, it's just a matter of performing well and being confident."
However, Marsh is fully aware that unless he keeps performing strongly then there will be no Test chances presenting itself going forward so all his focus is on the upcoming Twenty20 and one-day international clashes with England.
"I think it's really important that I take it one step at a time. I have a great opportunity to over there and cement myself in the T20 side and hopefully the one-dayers as well. I'm really excited about the opportunity," he said.
"When you get to my age you want to try and take your chances so I'm looking forward to it and it's going to be a great challenge. I'm just worrying about that at the moment and if I keep working hard, and training and playing well then we will see what happens down the future."
Marsh shone in the Australian A tour of South Africa recently highlighted by an unbeaten 136 against South Africa A and then 96 against India A, so he feels in good form physically and mentally about his game right now.
"I'm feeling really good. It was nice to get the confidence up in South Africa and get a few runs. I'm now going to England with a lot of confidence and I'm just looking forward to it," Marsh said.
"Definitely it has been a mentally and physically challenging time to get back, but it's something that I have worked really hard on and now I feel I can go over to England with a lot of confidence knowing I've done all the hard work."
