[T]his is a serious offence. It is not however one at the worst end of the scale: had this opening been wider, had there been a real potential for Mr Giffin to fall through, the seriousness of the offence would have been grave. Even though the measurement of the penetration was modest, it is not unknown that in building work people fall in such a way that they lose consciousness. There was water below. If it was that type of accident it would indeed, especially in the light of the history of this defendant, have been a very serious offence, but I am not able to come to that conclusion, although I conclude that it is a serious offence.
31 The appellant contended on appeal that the evidence on sentence disclosed that there was no prospect that an employee could have fallen into the water either through the bridge or over the edge of the bridge. It was therefore unlikely that Mr Giffin could have been rendered unconscious as a result of the accident. It was also said to be irrelevant to make reference to there being water below, as his Honour did, when assessing the consequences of the accident. Nevertheless the appellant conceded in oral submissions on the appeal that the offence was serious and that his Honour was correct in so finding.
32 As the authorities on this point have observed, the fact of serious injuries does not, of itself, demonstrate the objective seriousness of a breach of the Act, although the occurrence of serious injuries may manifest the degree of seriousness of the risk to safety: see for example Maddaford v CSR Limited and Mulgoa Quarries Pty Ltd [2004] NSWIRComm 337 at [17] [18] and [23].
33 The passage in the sentencing remarks which we have reproduced, in our view, does no more than reflect his Honour's consideration of the seriousness of the risk and, based on this finding at first instance, his Honour concluded that the offence before him was serious but not "very serious". The reference in the passage to there being water below did not affect this conclusion. We agree that the circumstances in the context of the gravity of the offence were such as to warrant the finding that the offence was serious. We also note the appellant's concession in the regard that the offence was serious.
