[28] It is made clear by s 280(8)(b) that to be complying the notice in fact given must be accompanied by group certificates for the three years immediately before the injury supporting the claim for lost earnings. The appellant's notice provided under the cover of the solicitor's letter of 11 April 2002 did not comply with that requirement in that all the required group certificates did not accompany the notice. It is clear from the notice that the appellant was making a claim for lost earnings. Some group certificates were provided pursuant to the obligation imposed by s 280(8), but 1997 and 1998 group certificates were not provided. To the extent that the reasoning of McGill DCJ in Jamieson v Council of the City of Gold Coast, [2000] QDC 468; DC No 148 of 2000, 1 March 2000, suggests that a claimant is only under an obligation pursuant to s 280 to see that documents in his possession at the time the notice is given accompany the notice it should not be followed. Documents referred to in s 280(8) must accompany the notice, otherwise it is non-complying; but, of course, WorkCover may waive non-compliance and should do so where a satisfactory explanation for the non-production is given. The initial response from WorkCover dated 15 May 2002 drew attention to the non compliance in this case. Essentially that was a response pursuant to s 282(2)(c) of the Act. On receipt of the letter from the appellant's solicitors of 16 May 2002, including an undertaking to provide copies of the group certificates if they should come to hand, WorkCover was prepared to treat the notice as complying with the requirements of s 280; that was the effect of the letter of 28 May 2002. The notice bearing date 5 April 2002 was deemed to be compliant with s 280 as and from 28 May 2002, and therefore the six month period referred to in s 285(2) ran from that date, being the date of waiver of non-compliance. That was certainly the view of WorkCover because it expressly said so in the letter of 28 May.
