Zack returns to see you and tells you that Penny has moved out of the matrimonial home with their 2 children 2 weeks ago. He shows you a letter from Penny's lawyers seeking that he pay Penny the following: A lumpsum of $12,000 within 7 days to pay for outstanding bills including telephone, electricity, health insurance, registration and insurance on her car, new tyres and urgent repairs to her car. $650 per week from 13 February 2021 for her ongoing expenses. Zack cannot understand the basis on which Penny can make these claims as she he pays for her rent. In addition, he deposited $25,000 into Penny's bank account when she left the matrimonial home. He also believes that Penny's boyfriend is living with her and sharing all household expenses. Apparently, Penny's boyfriend is a model and earns in excess of $250,000 p.a. Any relevant facts from Question 1 are applicable to this question.

Specifically referring to the facts and the relevant law, advise Zack of the matters that a court will consider in determining Penny's claims for maintenance and the merits of her claims
