McGrath said he was still undecided about his future and was only concentrating on the upcoming last two Tests of the Ashes. Earlier, the Daily Telegraph had reported that the veteran medium-pacer will carry his resignation to the Melbourne Test before hading it over to Cricket Australia to join Shane Warne in retirement.
However, McGrath categorically denied any such plans and rubbished the report.
''All I did was finish (the third Test) in Perth, come home and I've done nothing since and I've had journalists camped on the front door and hassling me at home and everything,'' McGrath told Sydney radio 2KY.
''For me, it's just another day at the office,'' he added as he tried to clear the air.
The 36-year-old's retirement has been a subject of wild speculation with reports suggesting that after Damien Martyn and Warne, McGrath would be the third high-profile member of the World Champion team to bid adieu to the game.
But McGrath denied having ever talked about immediate retirement and described the whole situation as funny.
''To be honest, I haven't said anything. It's funny where it all comes from,'' McGrath said.
''To me, I'm just preparing for another game. Nothing's changed since the end of the Perth Test match, apart from the fact that Shane Warne's retiring at the end of the Sydney Test,'' he added.
''So it's funny whether it's in his (Warne) wake and I'm being pulled along as well or whether the media think it's time for me to go, I don't know. All I'm saying is that, to me, it's business as usual,'' he explained.
After the Ashes finish next month Australia will not be playing any Test cricket for the 11 months and McGrath said it would give him ample time to make up his mind about his future plans.
''I wouldn't mind a bit of an off-season. It'll be good. I guess we'll have to wait and see. I'm heading down to Melbourne today. I'm still enjoying it. I'm still loving playing and I've still got a lot of cricket in me,'' he insisted.
McGrath admitted that it would seem a bit strange without Warne in the dressing room but asserted that he and the Australian team will get over the loss just as they did after Steve Waugh retired.
''It is like losing part of the family. I remember when Mark and Steve retired, it sort of does feel strange for a while,'' he said.
