[8] The applicant also seeks to argue that his plea of guilty was due to wrong legal advice, that he could not call a witness to give evidence by telephone. Even putting to one side the procedural difficulty mentioned earlier, I am not persuaded that there is any substance in this argument. The applicant has not established that his legal advice was incorrect, or that it had any real bearing on his plea of guilty. The applicant has produced an affidavit by a person who deposes that she was reluctant to go to Court, but happy enough to give phone evidence. The affidavit does not explain the relevance of her evidence, but had the applicant wished to call her, he could have caused a subpoena to be issued. He could also have called the mechanic who gave the statement which was tendered in the District Court had he wished to do so. The applicant has not given evidence that he was given any advice by his lawyers to the contrary. The applicant was of full age and apparently of sound mind and understanding when he entered his plea of guilty, and he entered that plea in the exercise of a free choice in his own interests. In these circumstances, his arguments that he was in fact not guilty of the offence are insufficient to establish a miscarriage of justice: see Meissner v The Queen [1995] HCA 41; (1995) 184 CLR 132 and R v GV [2006] QCA 394.
