This election in 1928 was a regular election for half the members of the Senate held at the same time as a general election for the House of Representatives; see terms of senators. The 1928 House of Representatives results can be seen here.

At this Senate election in 1928, an additional senator had to be elected for Queensland to fill a casual vacancy; note Narelle Miragliotta & Campbell Sharman, 'Managing Midterm Vacancies: Institutional Design and Partisan Strategy in the Australian Parliament 1901–2013', Australian Journal of Political Science, 52(3) 2017: 351-366.

In the table above, see the Glossary distinctions between Seats won by ticket and Seats won by party, and between Seats won by party and Seats held by party.

Electoral system: A preferental voting system had been adopted for Senate elections since the Commonwealth Electoral Act 1919 (No.31 of 1919) with each state being a multimember district. Section 7 provided that, for a valid ballot paper, voters had to rank at least one more than twice as many candidates as there were vacancies to be filled, and could rank more if they wished. This was a form of optional preferential voting; for this half-Senate election in 1928, it meant each voter had to rank at least 7 candidates (9 in Queensland with a casual vacancy).

Ballot design: Important changes were made to Senate ballot papers by the Commonwealth Electoral Act 1922 (No.14 of 1922). The previous single list of candidates had made it hard for voters to vote for a party ticket unless they knew the surnames of the relevant candidates. In the 1922 Electoral Act, section 4 permitted candidates to be grouped, implicitly by party, although the basis of the grouping was not specified. Candidates within each group were listed alphabetically. Those candidates who ran as Independents were in a separate, unmarked, group at the bottom of the ballot paper.

Section 11 of the 1922 Act stipulated that the groups were to be printed in the order of the average alphabetical value of the surnames in each group (see section 11(c)(i)-(iii) for the method of calculation). The groups were then printed on the ballot paper as groups A, B, C, ... so that the ballot paper looked like the model set out in section 28 Form E. Again, there was no explicit reference to party names so that voters had to rely on election publicity and party how-to-vote cards to find out the party affiliation of the groups.

Nationalist Party and Country Party: Although the various branches of the Country Party had won votes in several states at Senate elections in 1919 and 1922 they had not been successful in wining any Senate seats. By February 1923, the Nationalist Party had formed a coalition government with the Country Party under Prime Minister Bruce. This spurred cooperation between the Nationalist Party and the Country Party with the Country Party winning four Senate seats at the 1925 elections (one each in New South Wales, South Australia, Victoria and Western Australia). Tensions within the various state parties prevented such close arrangements being repeated in 1928 but the Country Party was successful in winning a Senate seat in Victoria and in Western Australia.

Precursor to joint tickets: The arrangements in some states between the two anti-Labor parties to support each other's candidates at this Senate election relied the two parties coordinating their campaigning. The cooperation was not extended to having candidates from both parties on the same joint ticket until the 1931 Senate election.
