Stop.

Mr J.B. D’ORAZIO: […] I will run through this chart. It summarises the whole daylight saving issue. The bottom of the graph shows the hours of zero to 24, which is normal Western Australian standard time. The hours at the top are daylight saving time, with the one-hour difference. It shows the business times in the eastern states, and the overlap with Western Australia. It shows the enormous benefits that daylight saving will have for business. That might seem small, but it is a huge factor.

Mr R.F. Johnson: Who prepared that graph?

Mr J.B. D’ORAZIO: Dr Hammer.

The green lines show sunrise and sunset. The blue line shows the evening meal time. The recreation time is highlighted here. The evening recreation time is shown as being half during sunlight hours and half not during sunlight hours. This is what it will be under daylight saving. The white part on the graph shows the time that is allowed for people to get home after work. The significant thing from my point of view – this is something that all members should look at – is the meal and recreation time. I call that family time.

Mr R.F. Johnson: Do we all have to eat at that time?

Mr J.B. D’ORAZIO: I would be happy to swap the blue and the orange lines for the member for Hillarys, because he is unusual! They are interchangeable. That shows how daylight saving will have the biggest benefit in giving families time to recreate together and engage in the activities that they enjoy.

There has been an interesting argument that daylight saving will result in a huge difference in temperatures. The graph shows the temperature rise, and also the temperature fall when the sea breeze comes in.

Mr R.F. Johnson: Is that every day? I find that astounding!

Mr J.B. D’ORAZIO: I am glad, member for Hillarys! I hope that at the end of this debate the member for Hillarys will be supporting daylight saving! The difference in temperatures because of the one-hour time difference will be between half a degree and one and a half degrees. It is not significant. The argument has been put that there will be a huge increase in temperatures, and school kids will die in the heat of the school bus. The reality is that the maximum increase in temperatures will be between half a degree and one and a half degrees. It will make very little difference. That is real data, not imaginary data.

Mr T.K. Waldron interjected.

Mr J.B. D’ORAZIO: I am not going to win the argument with the members of the National Party.

Mr R.F. Johnson: You have convinced me, my friend! That graph is absolutely astounding!

Mr J.B. D’ORAZIO: I like the member for Hillarys’ humour! I am very serious about the fact that daylight saving will be of enormous benefit for business. More importantly, it is about lifestyle and families, and about tackling the health issue in our community.

Mr C.J. Barnett: I think we need a photo of you holding up that graph!

Mr J.B. D’ORAZIO: I am sure I will have many to give the member!

Mr D.T. Redman: Is it correct that the hottest time of the day is actually four o’clock?

Mr J.B. D’ORAZIO: On the day shown on this graph, the temperature peaked at four o’clock. It will peak at five o’clock during daylight saving hours. As I have said, the difference in temperatures because of the one-hour time difference will be between half a degree and one and a half degrees.

Mr R.F. Johnson: Do you give a guarantee with that?

Mr J.B. D’ORAZIO: The member for Mindarie has given an unequivocal guarantee that if anyone’s curtains fade because of the introduction of daylight saving, he will replace them.

Mr R.F. Johnson: I have a pair of curtains at home that have faded!
