We think voters will vote on average a few times a year on major issues or issues that interest them. In 2015 nearly 80% of Australians had access to a smartphone(1). Voters can vote at any time during the duration of a Bill in Parliament, which is often months and we have put a mechanism in place to ensure it is at least 6 weeks, see "What is a sunset clause?". Voters who don't have internet access can go to the library, get help from family or friends who have a smartphone or tablet, or those in nursing homes will likely have a carer who can help during this period. In extreme circumstances, we have a mobile voting unit.
