| 2. Virological surveillance | 2.1. ARI / ILI specimens for virus typing & subtyping | Sentinel labs & 2 NIC | Sentinel labs (NISN) & 1 NIC | 2 NIC | 
| 2.2. ARI / ILI specimens for virus genome sequencing | 1 WHO CC and H5 lab | 1 WHO CC and H5 lab | None | |
| 2.3. ARI / ILI specimens for antiviral drug resistance | ||||
| 3. Community surveillance | 3.1. Notified biologically/laboratory-confirmed cases | Sentinel labs, Mandatory disease notification (NNDSS) | Mandatory disease notification (NIDRS) | None | 
| 4. Outbreak surveillance | 4.1. ARI/ILI outbreaks in close settings | Outbreak monitoring in Australian states | 
 Outbreaks in close settings (CPHEMIS)  | 
Unpublished | 
| 4.2. Biologically /laboratory-confirmed outbreaks in close settings | Unpublished | |||
| 5. Primary care syndromic surveillance | 5.1. ARI/ILI GP visits and/or incidence rates | Sentinel GPs (ASPREN) | None | ILI sentinel clinics | 
| 5.2. Biologically/ laboratory-confirmed GP visits and/or incidence rates | None | |||
| 5.3. Influenza-associated excess GP visits | None | None | None | |
| 5.4. Influenza-associated excess work loss cases | None | None | None | |
| 6. Hospital syndromic surveillance | 6.1. ILI or biologically/laboratory-confirmed emergency department visits | ILI EDs (PHREDSS some states only - NSW) | ILI sentinel emergency departments (NISN) | None | 
| 6.2. SARI/ILI hospital admissions | SARI sentinel hospitals (FluCAN & APSU) | SARI sentinel hospitals scheme | SARI sentinel hospitals | |
| 6.3. Biologically/ laboratory-confirmed hospital admissions | ||||
| 6.4. Influenza-associated excess hospital admissions | None | None | None | |
| 6.5 Biologically/ laboratory-confirmed ICU admissions | SARI sentinel hospitals (FluCAN & APSU) | SARI sentinel hospitals system | SARI sentinel hospitals | |
| 7. Mortality surveillance | 7.1 Diagnosed or biologically/laboratory-confirmed influenza deaths | Mandatory disease notification (NNDSS) | Mandatory disease notification (NIDRS) | None | 
| 7.2. Influenza-associated excess deaths | Influenza & pneumonia (some states only - NSW) | None | None | 
None = there are no surveillance tools covering this outcome; unpublished = these outcomes are covered by surveillance tools but the data are not published in the weekly or annual reports
