There are also about 320,500 invertebrate species, of which insects are the largest class, accounting for more than 75% of all animal species. Australia has over 15,000 known species of fungi although it is possible that tens of thousands more exist.
Australia's wildlife show many adaptations to their environments. As the leaves of most plants are poor in nutrients, Australia has a high proportion of birds, insects and marsupials, such as the

In the Senate (the upper house), there are 76 senators: twelve each from the states and two each from the mainland territories (the Australian Capital Territory and the Northern Territory).
The House of Representatives (the lower house) has 150 members elected from single-member
electoral divisions, commonly known as "electorates" or "seats", allocated to states on the basis of population, with each of the current states guaranteed a minimum of five seats. The lower house has a maximum term of three years, but this is not fixed and governments usually dissolve the house early for an election at some point in the 6 months before the maximum. Elections for both chambers are generally held simultaneously with senators having overlapping six-year terms except for those from the territories, whose terms are not fixed but are tied to the electoral cycle for the lower house. Thus only 40 of the 76 places in the Senate are put to each election unless the cycle is interrupted by a

Health
Australia's life expectancy of 83 years (81 years for males and 85 years for females) is the List of countries by life expectancy, fifth-highest in the world. It has the highest rate of skin cancer in the world, while Tobacco smoking, cigarette smoking is the largest preventable cause of death and disease, responsible for 7.8% of the total mortality and disease.

Following a period in which access to the scheme was restricted, the scheme became Universal health care, universal once more in 1981 under the name of Medicare (Australia), Medicare. The program is nominally funded by an income tax surcharge known as the Medicare levy, currently at 2%. The states manage hospitals and attached outpatient services, while the Commonwealth funds the Pharmaceutical Benefits Scheme (subsidising the costs of medicines) and general practice.
Education
School attendance, or registration for Homeschooling in Australia, home schooling, is compulsory throughout Australia. Education is primarily the responsibility of the individual states and territories; however, the Commonwealth has significant influence through funding agreements. Since 2014, Australian Curriculum, a national curriculum developed by the Commonwealth has been implemented by the states and territories. Attendance rules vary between states, but in general children are required to attend school from the age of about 5 until about 16. In some states (Western Australia, Northern Territory and New South Wales), children aged 16–17 are required to either attend school or participate in vocational training, such as an apprenticeship. According to the 2022 PISA evaluations, Australian 15-year-olds ranked ninth in the OECD for reading and science and tenth for maths. However, less than 60% of Australian students achieved the National Proficiency Standard – 51% in maths, 58% in science and 57% in reading.
Australia has an adult literacy rate that was estimated to be 99% in 2003.
However, a 2011–2012 report for the Australian Bureau of Statistics found that 44% of the population does not have high literary and numeracy competence levels, interpreted by others as suggesting that they do not have the "skills needed for everyday life".
Australia has 37 government-funded universities and three private universities, as well as a number of other specialist institutions that provide approved courses at the higher education level. The OECD places Australia among the most expensive nations to attend university. There is a state-based system of vocational training, known as Technical and further education, TAFE, and many trades conduct apprenticeships for training new tradespeople. About 58% of Australians aged from 25 to 64 have vocational or tertiary qualifications and the tertiary graduation rate of 49% is the highest among OECD countries. 30.9% of Australia's population has attained a higher education qualification, which is among the highest percentages in the world.
Australia has the highest ratio of International students in Australia, international students per head of population in the world by a large margin, with 812,000 international students enrolled in the nation's universities and vocational institutions in 2019. Accordingly, in 2019, international students represented on average 26.7% of the student bodies of Australian universities. International education therefore represents one of the country's largest exports and has a pronounced influence on the country's demographics, with a significant proportion of international students remaining in Australia after graduation on various skill and employment visas. Education is Australia's third-largest export, after iron ore and coal, and contributed more than $28 billion to the economy in the 2016–17 financial year.

Culture
Contemporary Australian culture is diverse

New citizens and visa holders are required to commit to "Australian values", which are identified by the Department of Home Affairs (Australia), Department of Home Affairs as including: a respect for the freedom of the individual; recognition of the rule of law; opposition to racial, gender and religious discrimination; and an understanding of the ":wikt:fair go, fair go", which is said to encompass the equality of opportunity for all and compassion for those in need.

While the school remained influential into the 1900s, modern art, modernists such as Margaret Preston and Clarice Beckett, and, later, Sidney Nolan, explored new artistic trends.
The landscape remained central to the work of Aboriginal watercolourist Albert Namatjira, as well as Fred Williams (artist), Fred Williams, Brett Whiteley and other post-war artists whose works, eclectic in style yet uniquely Australian, moved between the figurative art, figurative and the abstract art, abstract.

It has increased in popularity among non-Indigenous Australians since the 1970s, with examples such as Backhousia citriodora, lemon myrtle, the Macadamia, macadamia nut and kangaroo meat now widely available.
The first colonists introduced British cuisine, British and Irish cuisine to the continent.
