Two separate cases of people contravening orders, and given jail terms. (I'm okay with this part, rules are rules, especially in a pandemic)

Why did the woman who breached the order once get 4 weeks jail, and the man that did it twice only get 21 days, served concurrently?

I'm going to start threading these, because the sentences are wildly different for people breaking the same law.

69 year old man gets 6 days jail.

42-year-old man gets 12 days jail.

52 year old man gets 7 days jail, suspended. 23 year old woman gets 7 days jail, suspended.

67 year old man gets 7 days jail suspended (for 2 contraventions!)

55 year old woman gets two weeks jail.

39 year old man gets two weeks jail.

56 year old man gets 7 days jail for 2 offences.

79 year old woman gets 14 days jail, suspended for 12 months.

(I'm ok with this)

3 cases, again wildly different outcomes, and again, if you're a woman you're probably going to jail, and if you're a man, you might get off.

48yo woman, 1 breach - 10 days jail.
20yo man, 3 breaches - 8 weeks jail, suspended for 2 years
37yo woman, 3 breaches, four weeks jail.

29-year-old woman sentenced to 14 days prison.

We have a record breaking jail sentence (here's a shock, it's a woman).

54-year-old woman sentenced to 8 weeks jail for 1 breach.

53-year-old woman was sentenced to 14 days jail.

33-year-old male gets $15000 fine for two breaches.

46-year-old woman gets 14 days jail for two breaches.

67-year-old male sentenced to 6 days jail, suspended for 12 months, for trying to leave Hong Kong while in home quarantine.

A 19-year-old woman sentenced to 14 days' imprisonment, suspended for 12 months for leaving quarantine twice in a two day period.

Now see, that seems like it should be a jailable offence without suspension. I can't make heads nor tails of these decisions.
