Oxford press grammar curriculum - I personally prefer Oxford over Macmillan because I have used their reading series (free samples on Oxford owl) and it is great. Textbooks for all subjects across all age levels available for Australia.
The Ancient Near Eastern World (World in Ancient Times published by Oxford Press). Wholes series for grades 8 and up (though I think grades 5 and up): student text, student guide/workbook, teacher book. homeschool history curriculum
