[16] The comparable sentences referred to us by the appellant were, in approximate chronological order, Bouma (CA No 261 of 1988, 2 February 1989), Robertson (CA No 103 of 1989, 18 July 1989), Vickery (CA No 62 of 1992, 12 June 1992), R v Melano [1994] QCA 523; [1995] 2 QdR 186, Darwin (CA No 98 of 1996, 4 June 1996), Hamilton (CA No 440 of 1996, 6 December 1996), Maguire (CA No 490 of 1996, 4 February 1997), Anders (CA No 571 of 1996, 25 July 1997), Hallett (CA No 100 of 1997, 19 June 1997), Comerford (CA No 274 of 1997, 27 August 1997) and Cooney (CA No 386 of 1997, 6 March 1998). As mentioned earlier, all of them were sentences for unlawful wounding involving the use of a beer glass or, on one occasion each, a beer jug (Robertson) and a beer bottle (Bouma) and resulted in sentences of between one and three years imprisonment. However some of them, either because of the higher degree of criminality involved or because they involved offenders with more serious prior criminal histories or involved conviction after a trial, or because of a combination of these factors, are not useful comparisons. We shall refer only to those which are most directly comparable to this.
