Australian law recognises only monogamous marriages, being marriages of two people, including same-sex marriages, and does not recognise any other forms of union, including traditional Aboriginal marriages, polygamous marriages or concubinage.
By definition you cannot have a polygamous marriage in Australia without being married to two people at once, which would make you guilty of the criminal offence of bigamy. Thus, polygamy in Australia is not legal.
In short, no. Most places in the world do not permit a legally recognized marriage union between more than two people (often a man and a woman).
You must be at least 18 years old to get married, unless one of you is aged between 16 and 18 and: you have court approval by a judge or magistrate to marry. consent by your parent or guardian has been given or dispensed with.
Marriage and multiple relationships
Australian law recognises both marriages and de facto relationships. While bigamy is a criminal offence (under section 94 of the Marriage Act 1961), it is not an offence to have multiple simultaneous de facto relationships.
In Australia, it is illegal to enter into multiple marriages, or to be married to more than one person at a time. Being married to multiple people at the same time is known as polygamy. To be in a polygamous marriage you need to commit the act of Bigamy, which is a criminal offence in Australia.
For example, say a general partnership has three partners. One of the partners takes out a loan that the business cannot repay. All partners may now be personally liable for the debt. General partnerships are easy to form and dissolve.
Australian law prohibits blood relatives from marrying and this includes adopted as well as natural children. Cousins are not prohibited from marrying one another.
You can marry other types of relatives or people from your household including aunts, uncles, cousins, step siblings and foster siblings.
The Australian Marriage Act 1961 prohibits marriages with minors, more than one person at once, a parent, grandparent, child, grandchild, brother or sister and a person of the same sex. It does not exclude nieces or nephews from marrying aunties or uncles.
Basically, you and your partner get 3 hours a week of uninterrupted alone time. You can take those 3 hours all at once OR break it up into a half hour here, an hour there, etc. You also get 3 hours of uninterrupted TOGETHER time. Some women say this has done amazing things for their relationships.
No state permits its citizens to enter into more than one concurrent, legally-licensed marriage. People who attempt to, or are able to, secure a second marriage license are generally prosecuted for bigamy. The terms "bigamy" and "polygamy" are sometimes confused or used interchangeably.
All U.S. jurisdictions prohibit polygamy by invalidating marriages involving more than two spouses. State laws against bigamy—getting married to someone while still legally married to another person—are usually grounds for an annulment. Similar to divorce, an annulment results in the termination of a marriage.
Under Australian law, however, it is not illegal to have multiple de facto relationships at the one time. Section 4AA(5)(b) of the Family Law Act explicitly allows that “a de facto relationship can exist even if one of the persons is legally married to someone else or in another de facto relationship”.
Thus polygamy became illegal in India in 1956, uniformly for all of its citizens except for Muslims, who are permitted to have four wives and for Hindus in Goa and along the western coast where bigamy is legal. A polygamous Hindu marriage is null and void.
Adultery is not a crime in Australia. Under federal law enacted in 1994, sexual conduct between consenting adults (18 years of age or older) is their private matter throughout Australia, irrespective of marital status.
In the United States, second cousins are legally allowed to marry in every state. However, marriage between first cousins is legal in only about half of the American states. All in all, marrying your cousin or half-sibling will largely depend on the laws where you live and personal and/or cultural beliefs.
The vast majority of children of first cousins are healthy and do not have problems due to their parents' relatedness. It is important to keep in mind that even for an unrelated couple, there is an approximately 2-3% chance that their child is born with a birth defect, genetic syndrome, or disability.
In short, yes, it is legal for second and third cousins to marry in the US. Beyong that, state laws get a little more complicated. According to the National Conference of State Legislatures: "Twenty-five states prohibit marriages between first cousins.

An avunculate marriage is a marriage with a parent's sibling or with one's sibling's child—i.e., between an uncle or aunt and their niece or nephew. Such a marriage may occur between biological (consanguine) relatives or between persons related by marriage (affinity).
A partnership must consist of at least two people and a maximum of twenty people. A partnership is also not continuous. If one of the partners withdraw from the partnership or one of the partners pas away, the partnership will dissolve.
