no, it is not destination-based, its based on sections. You get different cards depending on how far your destination is.
If it is from around Epping to Macquarie, then you probably need a 'section 6-9' travel ten card, which is about 12$. I have this and i can travel from kissing point/Kirby street bustop to maquarie and that is about 8 sections.
Instead of saying a section 6-9 travel ten card, just ask for a 'red' travel ten card, maximum 9 sections :/
EDIT: ok, i just read the other posts and apparently epping is a lot closer than i thoguht, so maybe you can get a cheaper ticket, say max 6 section :/
