Delta AIC rankings of the importance of vector, host and transmission parameters explored in mechanistic model combinations (Scenarios as outlined in Table 3) fitted to RRV notifications.

Where, βvi the transmission rate from vectors to host species i; ρϑ the phase and amplitude of seasonal transmission; ωi host recrudescence of host species i; v primary vector population; and v2 secondary vector population. Host and vector species i are defined as kangaroos/wallabies, k; possums, p; and humans, h. Best fitting models (ΔAIC < 4) are in bold, with the most likely model fit having a ΔAIC = 0.
